CHAPTER 7
Design for Quality and Product Excellence
Teaching Notes
The precise manner in which a person or team approaches product design, solving problems to
achieve product excellence, or developing product reliability is not as critical as doing it in a
systematic fashion. Students have been exposed to process management and improvement in
Chapter 7, but they may still have some difficulty in understanding how measurement
(metrology) and Six Sigma projects can be used at the design stage to make frequent, but gradual
changes as an approach to process improvement.
Key objectives for this chapter should include:
• To explore the typical structured product development process consisting of idea
generation, preliminary concept development, product/process development, full-scale
production, product introduction, and market evaluation.
• To learn that concurrent, or simultaneous, engineering is an effective approach for
managing the product development process by using multi-functional teams to help
remove organizational barriers between departments and therefore reduce product
development time. Design reviews help to facility product development by stimulating
discussion, raising questions, and generating new ideas
• To introduce the concept of Design for Six Sigma (DFSS) consisting of a set of tools and
methodologies used in the product development process to ensure that goods and services
meet customer needs and achieve performance objectives, and that the processes used to
make and deliver them achieve Six Sigma capability. DFSS consists of four principal
activities of: Concept development, Design development, Design optimization, and
Design verification. These activities are often incorporated into a variation of the
DMAIC process, known as DMADV, which stands for Define, Measure, Analyze,
Design, and Verify.
• To define concept development as the process of applying scientific, engineering, and
business knowledge to produce a basic functional design that meets both customer needs
and manufacturing or service delivery requirements. This involves developing creative
ideas, evaluating them, and selecting the best concept.
Design for Quality and Product Excellence 2
• To appreciate the concepts of innovation and creativity. Innovation involves the
adoption of an idea, process, technology, product, or business model that is either new or
new to its proposed application. Creativity is seeing things in new or novel ways. Many
creativity tools are designed to help change the context in which one views a problem or
opportunity, thereby leading to fresh perspectives.
• To explore Quality Function Deployment (QFD) -- a planning process to guide the
design, manufacturing, and marketing of goods by integrating the voice of the customer
throughout the organization. A set of matrices, often called the House of Quality, is used
to relate the voice of the customer to a product’s technical requirements, component
requirements, process control plans, and manufacturing operations.
• To investigate manufacturing specifications, consisting of nominal dimensions and
tolerances. Nominal refers to the ideal dimension or the target value that manufacturing
seeks to meet; tolerance is the permissible variation, recognizing the difficulty of
meeting a target consistently.
• Tolerance design involves determining the permissible variation in a dimension. A
scientific approach to tolerance design uses the Taguchi loss function. Taguchi assumes
that losses can be approximated by a quadratic function so that larger deviations from
target correspond to increasingly larger losses. For the case in which a specific target
value, T, is determined to produce the optimum performance, and in which quality
deteriorates as the actual value moves away from the target on either side (called
“nominal is best”), the loss function is represented by L(x) = k(x - T)2
.
• To study the dimensions of reliability—the ability of a product to perform as expected
over time. Formally, reliability is defined as the probability that a product, piece of
equipment, or system performs its intended function for a stated period of time under
specified operating conditions. In practice, the number of failures per unit time
determines reliability during the duration under consideration (called the failure rate),
look at functional failure at the start of product life (The early failure period is
sometimes called the infant mortality period), reliability failure after some period of
use.
• To understand why reliability is often modeled using an exponential probability
distribution and use the reliability function, specifying the probability of survival, which
is: R(T) = 1 – e-T
.
• To explore systems composed of individual components with known reliabilities,
configured in series, in parallel, or in some mixed combination, and how it ties into
various aspects of design, including optimization, tolerance design, and design
verification.
• To learn that design optimization includes setting proper tolerances to ensure maximum
product performance and making designs robust; a scientific approach to tolerance
design uses the Taguchi loss function. Techniques for design verification include
Design for Quality and Product Excellence 3
formal reliability evaluation, using techniques such as accelerated life testing and burn-
in.
• To examine the characteristics of Design Failure Mode And Effects Analysis
(DFMEA) -- a methodology to identify all the ways in which a failure can occur, to
estimate the effect and seriousness of the failure, and to recommend corrective design
actions.
• Fault Tree Analysis (FTA), sometimes called cause and effect tree analysis, is a
method to describe combinations of conditions or events that can lead to a failure. In
effect, it is a way to drill down and identify causes associated with failures and is a good
complement to DFMEA.
• To investigate good product design, which anticipates issues related to cost,
manufacturability, and quality. Improvements in cost and quality often result from
simplifying designs, and employing techniques such as design for manufacturability
(DFM) – the process of designing a product for efficient production at the highest level
of quality.
• To study social responsibilities in the design process including product safety and
environmental concerns, which have made Design for Environment (DfE) and design
for disassembly important features of products, because they permit easy removal of
components for recycling or repair, eliminate other environmental hazards, and makes
repair more affordable.
• To explore Design for Excellence (DFX), an emerging concept that includes many
design-related initiatives such as concurrent engineering, design for manufacturability
design for assembly, design for environment and other “design for” approaches. DFX
objectives include higher functional performance, physical performance, user
friendliness, reliability and durability, maintainability and serviceability, safety,
compatibility and upgradeability, environmental friendliness, and psychological
characteristics.
• To introduce concept engineering (CE) -- a focused process for discovering customer
requirements and using them to select superior product or service concepts that meet
those requirements.
• To appreciate that the purpose of a design review is to stimulate discussion, raise
questions, and generate new ideas and solutions to help designers anticipate problems
before they occur.
• To understand techniques for design verification including formal reliability evaluation.
These include accelerated life testing, which involves overstressing components to
reduce the time to failure and find weaknesses; and burn-in, or component stress testing,
which involves exposing integrated circuits to elevated temperatures in order to force
latent defects to occur.
Design for Quality and Product Excellence 4
• To appreciate that Six Sigma performance depends on reliable measurement systems.
Common types of measuring instruments used in manufacturing today fall into two
categories: “low-technology” and “high-technology.” Low-technology instruments are
primarily manual devices that have been available for many years; high-technology
describes those that depend on modern electronics, microprocessors, lasers, or advanced
optics.
ANSWERS TO QUALITY IN PRACTICE KEY ISSUES
Testing Audio Components at Shure, Inc.
1. The general definition of reliability as: the probability that a product, piece of equipment,
or system performs its intended function for a stated period of time under specified
operating conditions, is thoroughly tested by Shure. Tests are tailored to various market
segments, according to the type of use (or abuse) the equipment is likely to incur. For the
consumer market, Shure uses the cartridge drop and scrape test, which is particularly
important to test for, in the light of how “scratch” DJ’s use the equipment. For
presentation and installation audio systems, they use the microphone drop test and
perspiration test. For mobile communications, the two above tests, temperature, and cable
and cable assembly flex tests are applicable. For the performance audio, the microphone
drop test, perspiration test, sequential shipping, cable and cable assembly flex, and
temperature storage would all be appropriate. The purpose of the tests is to simulate
actual operating conditions so that the products can sustain accidents and rough handling
and perform effectively over a useful life. Quality characteristics that are studied are
achieved reliability and performance.
2. For the microphone drop test, the measures are probably variable measures of sound and
response levels, within an acceptable range. Thus, standard variables control charts may
be used. For the perspiration test, it may be that a p-chart or u-chart is used for attribute
measures. The cable and cable assembly flex test might use a p-chart to measure the
percentage of cables tested that failed due to rocking motions or twisting motions. The
sequential shipping tests would probably show varying proportions of failures due to
dropping, vibration, and rough handling. These might be sorted out using a Pareto chart.
Then efforts could be made to improve the most frequently occurring causes. The
cartridge drop and scrape test could also use p- or np-charts (see Chapter 13) to show
results per sample of 100 repetitions of the test. The temperature tests would most likely
use standard variables charts to measure whether test performance was within control
limits, or not.
Applying QFD in a Managed Care Organization
1. Although this example of QFD involved the design of a tangible items, it is more difficult
to implement in a service context, as opposed to a pure manufacturing context, because
Design for Quality and Product Excellence 5
both customer requirements and technical requirements are harder to quantify and assess
that with tangible products.
2. The detailed calculations in the Importance of the hows row and Percentage of
importance of the hows row used to arrive at these figures can be shown and verified on
the spreadsheet labelled QIP-QFD Healthcare.xlsx. Note that some discrepancies
involving incorrect multiplication, were found in part of the QFD “House of Quality.”

The numbers in the original table were verified by the calculations shown above (some columns of the original table were rearranged for convenience
of calculation). The rates of improvement, absolute weights, and percent improvements, based on the given values for “rate of importance” and
“company now” and “plan” were validated. As in the original table, the “importance of hows” and “percent of importance of hows” turned out to be
accurately calculated. Specific factors shown as the most important were “glossary terms” and “updates.”
Design for Quality and Product Excellence 7
3. The lessons that can be learned and applied to other service organizations that seek to
design or redesign their products and services include the facts that QFD provides for a
systematic approach to linking the “voice of the customer” to operational requirements.
By doing so, operating efficiencies can be realized and customer satisfaction can be
enhanced. In addition, employee satisfaction often can be improved, as well, as found in
the case. It must be recognized that time and effort is involved in gathering, sorting, and
analyzing the characteristics and factors. Also, there is subjectivity in applying ratings
and weights to variables. Hence, the results are not easy to predict and guarantees are
limited.
ANSWERS TO REVIEW QUESTIONS
1. Product design and development consists of six steps:
• Idea Generation. New or redesigned product ideas should incorporate customer
needs and expectations.
• Preliminary Concept Development. In this phase, new ideas are studied for
feasibility.
• Product/Process Development. If an idea survives the concept stage, the actual
design process begins by evaluating design alternatives and determining
engineering specifications for all materials, components, and parts. This phase
usually includes prototype testing, design reviews, and development, testing, and
standardization of the manufacturing processes
• Full-Scale Production. If no serious problems are found, the company releases the
product to manufacturing or service delivery teams.
• Market Introduction. The product is distributed to customers.
• Market Evaluation. An ongoing product development process that relies on
market evaluation and customer feedback to initiate continuous improvements.
2. Competitive pressures are forcing companies to reduce time to market, which means that
the time for product development is also squeezed. The problems incurred in speeding up
the process are well known. If done too hastily, the result will be the need to revise or
scrap the design, cost increases or project over-runs, difficulty in manufacturing the
product, early product failure in the field, customer dissatisfaction, and/or lawsuits due to
product liability. One of them most significant impediments to rapid design is poor intra-
organizational coordination. Reducing time to market can only be accomplished by
process simplification, eliminating design changes, and improving product
manufacturability. This requires involvement and cooperation of many functional groups
to identify and solve design problems in order to reduce product development and
introduction time.
3. Concurrent engineering is a process in which all major functions involved with bringing a
product to market are continuously involved with product development from conception
through sales. Such an approach not only helps achieve trouble-free introduction of
products and services, but also results in improved quality, lower costs, and shorter
product development cycles. Concurrent engineering involves multifunctional teams,
usually consisting of 4 to 20 members and including every specialty in the company. The
Design for Quality and Product Excellence 8
functions of such teams are to perform and coordinate the activities in the product
development process simultaneously, rather than sequentially. Companies exploit
concurrent engineering to achieve a competitive advantage. Typical benefits include 30 to
70 percent less development time, 65 to 90 percent fewer engineering changes, 20 to 90
percent less time to market, 200 to 600 percent improvement in quality, 20 to 110 percent
improvement in white collar productivity, and 20 to 120 percent higher return on assets.
4. Design for Six Sigma (DFSS) uses a set of tools and methodologies in the product
development process to ensure that goods and services will meet customer needs and
achieve performance objectives, and that the processes used to make and deliver them
achieve Six Sigma capability. DFSS consists of four principal activities:
• Concept development, in which product functionality is determined based upon
customer requirements, technological capabilities, and economic realities;
• Design development, which focuses on product and process performance issues
necessary to fulfill the product and service requirements in manufacturing or delivery;
• Design optimization, which seeks to minimize the impact of variation in production
and use, creating a “robust” design; and
• Design verification, which ensures that the capability of the production system meets
the appropriate sigma level
5. Concept development is the process of applying scientific, engineering, and business
knowledge to produce a basic functional design that meets both customer needs and
manufacturing or service delivery requirements. Developing new concepts requires
innovation and creativity.
Innovation involves the adoption of an idea, process, technology, product, or business
model that is either new or new to its proposed application. The outcome of innovation is
a discontinuous or breakthrough change and results in new and unique goods and services
that delight customers and create competitive advantage.
Innovations can be classified as:
1. An entirely new category of product; for example the iPod
2. First of its type on the market in a product category already in existence; for
example, the DVD player.
3. A significant improvement in existing technology, such as the blu-ray player
4. A modest improvement to an existing product, such as the latest iPad.
Creativity is seeing things in new or novel ways. In Japanese, the word creativity
has a literal translation as “dangerous opportunity.” Many creativity tools, such as
brainstorming and Brainwriting—a written form of brainstorming, are designed to
help change the context in which one views a problem or opportunity, thereby
leading to fresh perspectives. A creativity tool that finds extensive use in product
design is TRIZ, which is a Russian acronym for the Theory of Inventive Problem
Solving. TRIZ was developed by a Russian patent clerk who recognized that
concepts of inventive problem solving could be taught, in order to foster creative
problem solving.
Design for Quality and Product Excellence 9
Concept development is an important tool for assuring quality because it provides a
systematic process that leaves a strong audit trail back to the voice of the customer. This
makes it difficult to challenge the results of skeptics and convert them. The process also
helps to build consensus and gives design teams confidence in selling their concept to
management. However, it takes a lot of discipline and patience.
6. Conceptual designs must be translated into measurable technical requirements and,
subsequently, into detailed design specifications. Detailed design focuses on establishing
technical requirements and specifications, which represent the transition from a
designer’s concept to a producible design, while also ensuring that it can be produced
economically, efficiently, and with high quality.
7. QFD benefits companies through improved communication and teamwork between all
constituencies in the production process, such as between marketing and design, between
design and manufacturing, and between purchasing and suppliers. Product objectives are
better understood and interpreted during the production process. Use of QFD determines
the causes of customer dissatisfaction, making it a useful tool for competitive analysis of
product quality by top management. Productivity as well as quality improvements
generally follow QFD. QFD reduces the time for new product development. QFD allows
companies to simulate the effects of new design ideas and concepts. Companies can
reduce product development time and bring new products into the market sooner, thus
gaining competitive advantage.
8. In the QFD development process, a set of matrices is used to relate the voice of the
customer to a product’s technical requirements, component requirements, process control
plans, and manufacturing operations. The first matrix, called the House of Quality,
provides the basis for the QFD concept.
Building the House of Quality consists of six basic steps:
* Identify customer requirements.
* Identify technical requirements.
* Relate the customer requirements to the technical requirements.
* Conduct an evaluation of competing products or services
* Evaluate technical requirements and develop targets.
* Determine which technical requirements to deploy in the remainder of the
production/delivery process.
The first House of Quality in the QFD process provides marketing with an important tool
to understand customer needs and gives top management strategic direction. Three other
“houses of quality” are used to deploy the voice of the customer to (in a manufacturing
setting) component parts characteristics, process plans, and quality control. The second
house applies to subsystems and components. At this stage, target values representing the
best values for fit, function, and appearance are determined. In manufacturing, most of
Design for Quality and Product Excellence 10
the QFD activities represented by the first two houses of quality are performed by
product development and engineering functions.
In the last two stages, the planning activities involve supervisors and production line
operators. In the third house, the process plan relates the component characteristics to key
process operations, the transition from planning to execution. Key process operations are
the basis for a control point. A control point forms the basis for a quality control plan
delivering those critical characteristics that are crucial to achieving customer satisfaction.
This is specified in the last house of quality. These are the things that must be measured
and evaluated on a continuous basis to ensure that processes continue to meet the
important customer requirements defined in the first House of Quality.
9. Manufacturing specifications consist of nominal dimensions and tolerances. Nominal
refers to the ideal dimension or the target value that manufacturing seeks to meet;
tolerance is the permissible variation, recognizing the difficulty of meeting a target
consistently. Traditionally, tolerances are set by convention rather than scientifically. A
designer might use the tolerances specified on previous designs or base a design decision
on judgment from past experience. Setting inappropriate tolerances can be costly, since
tolerance settings often fail to account for the impact of variation on product
functionality, manufacturability, or economic consequences. The Taguchi loss function is
a scientific approach to tolerance design. Taguchi assumed that losses can be
approximated by a quadratic function so that larger deviations from target cause
increasingly larger losses.
10. The Taguchi loss function is a useful concept for process design. Taguchi suggests that
there is not strict cut-off point that divides good quality from poor quality. Rather, he
assumed that losses can be approximated by a quadratic function so that larger deviations
from target correspond to increasingly larger losses. For the case in which a specific
target value, T, is determined to produce the optimum performance, and in which quality
deteriorates as the actual value moves away from the target on either side (called
“nominal is best”), the loss function is represented by L(x) = k(x - T)2
where x is any
actual value of the quality characteristic and k is some constant. Thus, (x – T) represents
the deviation from the target, and the loss increases by the square of the deviation.
11. Reliability is the probability that a product, piece of equipment, or system performs its
intended function for a stated period of time under specified operating conditions. There are
four key components of this definition, including probability, time, performance, and
operating conditions. All of these have to be considered in a comprehensive definition of
reliability. Probability allows comparison of different products and systems, time allows us
to measure the length of life of the product, performance relates to the ability of the product
to do what it was designed to do, and operating conditions specify to amount of usage and
the environment in which the product is used.
12. A functional failure is one incurred at the start of the product's life due to defective
materials, components, or work on the product. A reliability failure is one that is incurred
after some period of use. For example, if a new TV set suffers a blown picture tube during
Design for Quality and Product Excellence 11
the first week, it's a functional failure. There was obviously a defect in the manufacture of
the tube. If the vertical hold feature of the set goes out (perhaps 3 days after the 1 year
warranty is up), that is a reliability failure. It should reasonably be expected to last much
longer than one year, but it didn't.
13. Reliability engineers distinguish between inherent reliability, which is the predicted
reliability determined by the design of the product or process, and the achieved
reliability, which is the actual reliability observed during use. Achieved reliability can be
less than the inherent reliability due to the effects of the manufacturing process and the
conditions of use.
14. Failure rate is defined as the number of failures per unit of time during a specified time
period being considered. For example, if 15 MP-3 players were tested for 500 hours and
there were two failures of the units, the failure rate would be: 2 / (15 x 500) = 1 / 3750 or
0.000267.
15. The product life characteristics curve, is the so-called "bath-tub curve" because of its shape.
It is actually the failure rate curve, described above. Such curves can be used to understand
the distinctive failure rate patterns of various designs and products, over time.
16. The reliability function represents the probability that an item will not fail within a certain
period of time, T. It is directly related to the cumulative distribution function: F(T) =
1 - e-T
, that yields the probability of failures. Since F(T) is the probability of failure, the
reliability function, R(T) can be defined as the complement, e.g. probability of not failing:
R(T) = 1 - (1 - e-T
) = e-T
It can also be expressed using the mean time to failure (MTTF) value  as: R(T) = e-T/
17. The reliability of series, parallel, and series parallel is relatively easy to compute, given the
reliability of components in each system. For the series system, RS = R1R2R3. Thus
reliabilities are multiplicative.
For a parallel system, the relationships are a little more complex, since the units are designed
to use redundant components, so that if one unit fails the system can continue to operate.
The system reliability is computed as:
RS = 1 - [(1 - R1)(1 - R2)(1 - Rn)]
For series-parallel systems, the equivalent reliabilities of each parallel sub-system are
calculated, successively, until there are no more parallel sub-systems. The system is then
reduced to a serially equivalent system in which all component reliabilities can be
multiplied to get the final reliability value.
18. Robust design refers to designing goods and services that are insensitive to variation in
manufacturing processes and when consumers use them. Robust design is facilitated by
Design for Quality and Product Excellence 12
design of experiments to identify optimal levels for nominal dimensions and other tools
to minimize failures, reduce defects during the manufacturing process, facilitate assembly
and disassembly (for both the manufacturer and the customer), and improve reliability.
19. The purpose of Design Failure Mode and Effects Analysis (DFMEA) is to identify all the
ways in which a failure can occur, to estimate the effect and seriousness of the failure,
and to recommend corrective design actions. A DFMEA usually consists of specifying
the following information for each design element or function: Failure modes; effect of
the failure on the customer; severity, likelihood of occurrence, and detection rating;
potential causes of failure, and corrective actions or controls. A simple example of a
DFMEA for an ordinary household light socket is provided in the chapter.
20. Fault Tree Analysis (FTA), sometimes called cause and effect tree analysis, is a method
to describe combinations of conditions or events that can lead to a failure. In effect, it is
a way to drill down and identify causes associated with failures and is a good
complement to DFMEA. It is particularly useful for identifying failures that occur only
as a result of multiple events occurring simultaneously. In other words FTA is a tool for
carrying out the entire DFMEA process.
21. Product design can have a major impact on manufacturability. If careful thought and
planning is not done by the designer (or design team), the end product can end up being
difficult or impossible to build due to placement of components, methods for
attachments, “impossible” tolerances, difficulties in attaching or fastening components
and/or difficulties in getting the whole assembled “system” to work smoothly, even with
the highest quality components. In addition time, materials, and other resources may be
wasted unnecessarily due to a poor manufacturing design.
The concept of Design for Manufacturability (DFM) is the process of designing a product so
that it can be produced efficiently at the highest level of quality. Its goal is to improve
quality, increase productivity, reduce lead time (time to market, as well as manufacturing
time) and maintain flexibility to adapt to future market conditions.
22. Key design practices for high quality in manufacturing and assembly include: 1) analyze all
design requirements to assess proper dimensions and tolerances, 2) determine process , 3)
identify and evaluate possible manufacturing quality problems, 4) select manufacturing
processes that minimize technical risks, and 5) evaluate processes under actual
manufacturing conditions.
23. Social responsibilities in the design process include safety and environmental concerns,
which have made Design for Environment (DFE) and Design for Disassembly important
features of products. Legal and environmental issues are becoming critical in designing
products and services, today. Product safety and its consequences, product liability, should
be of primary concern because of the damage that hazardous designs can do to consumers of
the product. Also, liability lawsuits can do major damage to the financial health of an
organization, as well as its image and reputation in the marketplace. Records and
Design for Quality and Product Excellence 13
documentation relating to the design process are the best defense against liability lawsuits.
These would include records on prototype development, testing, and inspection results.
Environmental issues involve questions of whether “environmentally friendly” designs
(those that minimize damage to the environment in manufacture and product use) are being
developed, what impacts will the design of the product have on the environment when it is
scrapped, and how can consumers be given the most value for their money, while balancing
the other two issues? The above questions can often be addressed by considering it as a
“design for environment” concept (often combined with and “design for disassembly”).
What is the best design for repairability/recylability?
24. Design for Excellence (DFX) is an emerging concept that includes many design-related
initiatives such as concurrent engineering, design for manufacturability design for
assembly, design for environment and other “design for” approaches. DFX objectives
include higher functional performance, physical performance, user friendliness, reliability
and durability, maintainability and serviceability, safety, compatibility and
upgradeability, environmental friendliness, and psychological characteristics. DFX
represents a total approach to product development and design involves the following
activities:
• Constantly thinking in terms of how one can design or manufacture products better,
not just solving or preventing problems
• Focusing on “things done right” rather than “things gone wrong”
• Defining customer expectations and going beyond them, not just barely meeting them
or just matching the competition
• Optimizing desirable features or results, not just incorporating them
• Minimizing the overall cost without compromising quality of function
25. The purpose of a design review is to stimulate discussion, raise questions, and generate
new ideas and solutions to help designers anticipate problems before they occur. To
facilitate product development, a design review is generally conducted in three major
stages of the product development process: preliminary, intermediate, and final. The
preliminary design review establishes early communication between marketing,
engineering, manufacturing, and purchasing personnel and provides better coordination
of their activities. It usually involves higher levels of management and concentrates on
strategic issues in design that relate to customer requirements and thus the ultimate
quality of the product. The preliminary design review evaluates such issues as the
function of the product, conformance to customer’s needs, completeness of
specifications, manufacturing costs, and liability issues.
After the design is well established, an intermediate review takes place to study the
design in greater detail to identify potential problems and suggest corrective action.
Personnel at lower levels of the organization are more heavily involved at this stage.
Finally, just before release to production, a final review is held. Materials lists, drawings,
and other detailed design information are studied with the purpose of preventing costly
changes after production setup.
Design for Quality and Product Excellence 14
26. Methods of product testing for reliability include: life testing, accelerated life testing,
environmental testing and vibration and shock testing. In life and accelerated life testing the
product is tested until it fails. The latter speeds up the process by overstressing the item to
hasten its eventual failure. Environmental and shock tests are performed to determine the
product's ability to survive and operate under adverse conditions of heat, cold, or shock.
SOLUTIONS TO PROBLEMS
Note: Data sets for several problems in this chapter are available in the Excel workbook
C07Data on the Student Companion Site for this chapter accompanying this text. Click on the
appropriate worksheet tab as noted in the problem (e.g., Prob. 7-5) to access the data.

2. Newfonia, Inc., is working on a design for a new smartphone. Marketing staff conducted
extensive surveys and focus groups with potential customers to determine the
characteristics that the customers want and expect in a smartphone. Newfonia’s studies
have identified the most important customer expectations as
• Initial cost
• Reliability
• Ease of use
• Features
• Operating cost
• Compactness
Develop a set of technical requirements to incorporate into the design of a House of
Quality relationship matrix to assess how well your requirements address these
expectations. Refine your design as necessary, based upon the initial assessment.
Answer
2. Analysis of customer responses for Newfonia’s proposed smartphone indicates the
likelihood of several strong relationships between customer requirements and associated
technical requirements of the design, such as value vs. price; features vs. compactness; and
ease of use vs. features. Operating costs may possibly be distantly related to initial cost and
features. Technical characteristics required to translate the “voice of the customer” into
operational or engineering terms might be measures of purchase cost, operating programs
(e.g., BranchOS, or other similar systems), number and type of features, weight, dimensions,
battery life, cost of replacement batteries, and peripherals.
Design for Quality and Product Excellence 16
3. Newfonia, Inc. (Problem 2), faces three major competitors in this market: Oldphonia,
Simphonia, and Colliefonia. It found that potential consumers placed the highest
importance on reliability (measured by such things as freedom from operating system
crashes and battery life), followed by compactness (weight/bulkiness), followed by
flexibility (features, ease of use, and types of program modules available). The operating
cost was only occasionally noted as an important attribute in the surveys. Studies of their
products yielded the information shown in the table in C07Data file for Prob.7-3on the
Student Companion Site for this chapter. Results of the consumer panel ratings for these
competitors are also shown in that spreadsheet. Using this information, modify and
extend your House of Quality from Problem 1 and develop a deployment plan for the
new smartphone. On what attributes should the company focus its marketing efforts?
Answer
3. With the new data given for Newfonia’s potential customers, a partial House of Quality
for the design of the smartphone can be built, as shown below. Note the strong
relationships between customer requirements and associated technical requirements of
the smartphone design.
The inter-relationships of the roof are not shown (limitations of MSWord software), but
these may be sketched in. For example, they would show a strong inter-relationship between
size and weight.

This analysis suggests that Newfonia should try to position itself between Simfonia and
Colliefonia in price and features. It should build on the strength of the customer’s reliability
concern, keeping battery life near 35 hours and use a proven operating program, such as
BranchOS. Enough features (10) should be offered to be competitive. If Newfonia can
design a high-value smartphone and sell it at an attractive price (say, $250 or less), it
should be a very profitable undertaking.
4. Georgio’s Giant Gyros conducted consumer surveys and focus groups concerning a new
giant gyro sandwich design, and the facility to sell it, and identified the most important
customer expectations (not in any order of priority) as
• Tasty, attractive, moderately healthy food
• Speedy service
• An easy-to-read menu board
• Accurate order filling
• Perceived value
Develop only a set of technical requirements to incorporate into the design of the product
and its delivery. Use a House of Quality relationship matrix to assess how well your
requirements address these expectations. Include some technical dimensions that may be
used to measure tasty, attractive, and “healthy” food; speedy service, acceptable menu
boards, order accuracy, or perceived value. Refine your design as necessary based upon
the initial assessment.
Answer
4. Analysis of customer responses for Georgio’s Giant Gyros indicates that there are likely to
be several strong relationships between customer requirements and associated technical
requirements of the product and delivery system that Georgio designs (for example, a giant
gyro product). Some strong relationships may be seen between moistness/flavor and trans-
fat; calories/sodium/t-fat and nutrition; staffing levels and work procedures; kitchen capacity
and facility layout; value and price; etc..
Note the three customer response categories that are unrelated to the design of the gyros --
order accuracy, speedy service, and menu board. These factors will probably require a
separate analysis as part of a facility and process design, thus focusing on the product in one
case, and the service delivery system in the other.

5. Georgio’s Giant Gyros (Problem 4) acquired some additional information about product
characteristics. It found that consumers placed the highest importance on taste appeal
(especially flavor) and order accuracy, followed by healthy food (measured by sodium
content and calories), value, and service. The menu board was only casually noted as one
of the least important attributes in the surveys. Georgio faces three major competitors in
this market: Mario’s, Gyroking, and Antonio’s. Studies of their products yielded the
information shown in the worksheet tab Prob.7-4 in the Excel file C07Data on the
Student Companion Site for this chapter. Results of the consumer panel ratings for each
of these competitors can also be found there (a 1–5 scale, with 5 being the best). Using
this information, modify and extend your House of Quality from Problem 2 and develop
a deployment plan for a new gyro. Assume that a separate study will be made on the
physical facilities. On what attributes should the company focus its marketing efforts?
Answer
5. With the new data given in C07Data.xlsx for Prob. 7-05 for Georgio's customers, a partial
House of Quality for the design of the gyros can be built, as shown below. Note that the
relationships between customer requirements (flavor, health, value) and associated
technical requirements (% fat, calories, sodium, price) of the gyro design are strong. Note
also that the focus here is on design of the product, not the service aspects of order
accuracy and service.
The inter-relationships of the roof are not shown, due to the limitations of MS
Word® software. These may be sketched in. For example, they would show strong
inter-relationship between % t-Fat and calories.

ANSWER – CONTINUED
5. The Importance and Competitive Evaluation of customer requirements can be read
from the survey results in the data tables in spreadsheet Prob07-05.xlsx that are provided,
and placed under their respective columns
Georgio’s Giant Gyros technical requirements must be placed on a more equal basis, which
would best be shown as units/ounce, except for the percent fat value. These are shown
below.
Company Price/Oz. Calories/Oz.* Sodium/Oz.* Fat (%) *
Georgio's $0.545 80.0 159.1 13
Kingyro $0.567 85.3 124.0 23
Antonio's $0.542 90.0 158.3 16
* Lower is better
Thus, we can see from the competitive evaluation of technical characteristics and Georgio’s
targets, that if Georgio’s is already low in price per ounce, as well as calories, and percent
fat, its new product is leaner and healthier, as well as being cost effective. This analysis
suggests that Georgio’s might consider increasing its size and flavor, which may indirectly
affect its visual appeal, as well. However, Georgio has not targeted the size for an increase.
At the same time, it should build on the strength of the nutrition trend by keeping the percent
fat and sodium low. Georgio's has targeted sodium for a major reduction, from 159/oz. to
110/oz., and slightly reducing the number of calories per ounce, from 80 to 70, to be even
more competitive. The facilities need some minor improvements, but their work procedures
appear to be customer-pleasing. They merely need to hold the gains. If Georgio’s can
design a flavorful, healthy, 5.5 oz. gyro and continue to sell it at the current attractive
price or $3.00, it should be a very profitable undertaking.
6. A blueprint specification for the thickness of a refrigerator part at Refrigaria, Inc. is 0.300

14. In the production of Raphael Transformers, any output voltage that exceeds 120 ± 10
volts is unacceptable to the customer. Exceeding these limits results in an estimated loss
of $200. However, the manufacturer can adjust the voltage in the plant by changing a
resistor that costs $2.25.
a. Determine the Taguchi loss function.
b. Suppose the nominal specification is 120 volts. At what tolerance should the
transformer be manufactured, assuming that the amount of loss is represented by the cost
of the resistor?
Design for Quality and Product Excellence 25
Answer
14. a) The Taguchi Loss function is: L(x) = k (x - T)2
200 = k (100)2
k = 0.5
So, L(x) = 0.5 (x-T)2
b) $2.25 = 0.5 (x-120)2
4.50 = (x - 120)2
(x - T)Tolerance = 50
.
4 = 2.12 volts
2.12 = x - 120
 x = 122.12
15. At Elektroparts Manufacturers’ integrated circuit business, managers gathered data from
a customer focus group and found that any output voltage that exceeds 55 ± 0.5 volts was
unacceptable to the customer. Exceeding these limits results in an estimated loss of $75.
However, the manufacturer can still adjust the voltage in the plant by changing a resistor
that costs $2.00.
a. Determine the Taguchi loss function.
b. Suppose the nominal specification remains at 55 volts. At what tolerance should the
integrated circuit be manufactured, assuming that the amount of loss is represented by the
cost of the resistor?
Answer
15. a) The Taguchi Loss function is: L(x) = k (x - T) 2
75 = k (0.5)2
k = 300
So, L(x) = 300 (x-T)2
b) The Taguchi Loss function is: L(x) = k (x - T) 2
$2.00 = 300 (x-55)2
0.00667 = (x - 55)2
(x - T)Tolerance = 00667

  • 5. 1 CHAPTER 7 Design for Quality and Product Excellence Teaching Notes The precise manner in which a person or team approaches product design, solving problems to achieve product excellence, or developing product reliability is not as critical as doing it in a systematic fashion. Students have been exposed to process management and improvement in Chapter 7, but they may still have some difficulty in understanding how measurement (metrology) and Six Sigma projects can be used at the design stage to make frequent, but gradual changes as an approach to process improvement. Key objectives for this chapter should include: • To explore the typical structured product development process consisting of idea generation, preliminary concept development, product/process development, full-scale production, product introduction, and market evaluation. • To learn that concurrent, or simultaneous, engineering is an effective approach for managing the product development process by using multi-functional teams to help remove organizational barriers between departments and therefore reduce product development time. Design reviews help to facility product development by stimulating discussion, raising questions, and generating new ideas • To introduce the concept of Design for Six Sigma (DFSS) consisting of a set of tools and methodologies used in the product development process to ensure that goods and services meet customer needs and achieve performance objectives, and that the processes used to make and deliver them achieve Six Sigma capability. DFSS consists of four principal activities of: Concept development, Design development, Design optimization, and Design verification. These activities are often incorporated into a variation of the DMAIC process, known as DMADV, which stands for Define, Measure, Analyze, Design, and Verify. • To define concept development as the process of applying scientific, engineering, and business knowledge to produce a basic functional design that meets both customer needs and manufacturing or service delivery requirements. This involves developing creative ideas, evaluating them, and selecting the best concept.
  • 6. Design for Quality and Product Excellence 2 • To appreciate the concepts of innovation and creativity. Innovation involves the adoption of an idea, process, technology, product, or business model that is either new or new to its proposed application. Creativity is seeing things in new or novel ways. Many creativity tools are designed to help change the context in which one views a problem or opportunity, thereby leading to fresh perspectives. • To explore Quality Function Deployment (QFD) -- a planning process to guide the design, manufacturing, and marketing of goods by integrating the voice of the customer throughout the organization. A set of matrices, often called the House of Quality, is used to relate the voice of the customer to a product’s technical requirements, component requirements, process control plans, and manufacturing operations. • To investigate manufacturing specifications, consisting of nominal dimensions and tolerances. Nominal refers to the ideal dimension or the target value that manufacturing seeks to meet; tolerance is the permissible variation, recognizing the difficulty of meeting a target consistently. • Tolerance design involves determining the permissible variation in a dimension. A scientific approach to tolerance design uses the Taguchi loss function. Taguchi assumes that losses can be approximated by a quadratic function so that larger deviations from target correspond to increasingly larger losses. For the case in which a specific target value, T, is determined to produce the optimum performance, and in which quality deteriorates as the actual value moves away from the target on either side (called “nominal is best”), the loss function is represented by L(x) = k(x - T)2 . • To study the dimensions of reliability—the ability of a product to perform as expected over time. Formally, reliability is defined as the probability that a product, piece of equipment, or system performs its intended function for a stated period of time under specified operating conditions. In practice, the number of failures per unit time determines reliability during the duration under consideration (called the failure rate), look at functional failure at the start of product life (The early failure period is sometimes called the infant mortality period), reliability failure after some period of use. • To understand why reliability is often modeled using an exponential probability distribution and use the reliability function, specifying the probability of survival, which is: R(T) = 1 – e-T . • To explore systems composed of individual components with known reliabilities, configured in series, in parallel, or in some mixed combination, and how it ties into various aspects of design, including optimization, tolerance design, and design verification. • To learn that design optimization includes setting proper tolerances to ensure maximum product performance and making designs robust; a scientific approach to tolerance design uses the Taguchi loss function. Techniques for design verification include
  • 7. Design for Quality and Product Excellence 3 formal reliability evaluation, using techniques such as accelerated life testing and burn- in. • To examine the characteristics of Design Failure Mode And Effects Analysis (DFMEA) -- a methodology to identify all the ways in which a failure can occur, to estimate the effect and seriousness of the failure, and to recommend corrective design actions. • Fault Tree Analysis (FTA), sometimes called cause and effect tree analysis, is a method to describe combinations of conditions or events that can lead to a failure. In effect, it is a way to drill down and identify causes associated with failures and is a good complement to DFMEA. • To investigate good product design, which anticipates issues related to cost, manufacturability, and quality. Improvements in cost and quality often result from simplifying designs, and employing techniques such as design for manufacturability (DFM) – the process of designing a product for efficient production at the highest level of quality. • To study social responsibilities in the design process including product safety and environmental concerns, which have made Design for Environment (DfE) and design for disassembly important features of products, because they permit easy removal of components for recycling or repair, eliminate other environmental hazards, and makes repair more affordable. • To explore Design for Excellence (DFX), an emerging concept that includes many design-related initiatives such as concurrent engineering, design for manufacturability design for assembly, design for environment and other “design for” approaches. DFX objectives include higher functional performance, physical performance, user friendliness, reliability and durability, maintainability and serviceability, safety, compatibility and upgradeability, environmental friendliness, and psychological characteristics. • To introduce concept engineering (CE) -- a focused process for discovering customer requirements and using them to select superior product or service concepts that meet those requirements. • To appreciate that the purpose of a design review is to stimulate discussion, raise questions, and generate new ideas and solutions to help designers anticipate problems before they occur. • To understand techniques for design verification including formal reliability evaluation. These include accelerated life testing, which involves overstressing components to reduce the time to failure and find weaknesses; and burn-in, or component stress testing, which involves exposing integrated circuits to elevated temperatures in order to force latent defects to occur.
  • 8. Design for Quality and Product Excellence 4 • To appreciate that Six Sigma performance depends on reliable measurement systems. Common types of measuring instruments used in manufacturing today fall into two categories: “low-technology” and “high-technology.” Low-technology instruments are primarily manual devices that have been available for many years; high-technology describes those that depend on modern electronics, microprocessors, lasers, or advanced optics. ANSWERS TO QUALITY IN PRACTICE KEY ISSUES Testing Audio Components at Shure, Inc. 1. The general definition of reliability as: the probability that a product, piece of equipment, or system performs its intended function for a stated period of time under specified operating conditions, is thoroughly tested by Shure. Tests are tailored to various market segments, according to the type of use (or abuse) the equipment is likely to incur. For the consumer market, Shure uses the cartridge drop and scrape test, which is particularly important to test for, in the light of how “scratch” DJ’s use the equipment. For presentation and installation audio systems, they use the microphone drop test and perspiration test. For mobile communications, the two above tests, temperature, and cable and cable assembly flex tests are applicable. For the performance audio, the microphone drop test, perspiration test, sequential shipping, cable and cable assembly flex, and temperature storage would all be appropriate. The purpose of the tests is to simulate actual operating conditions so that the products can sustain accidents and rough handling and perform effectively over a useful life. Quality characteristics that are studied are achieved reliability and performance. 2. For the microphone drop test, the measures are probably variable measures of sound and response levels, within an acceptable range. Thus, standard variables control charts may be used. For the perspiration test, it may be that a p-chart or u-chart is used for attribute measures. The cable and cable assembly flex test might use a p-chart to measure the percentage of cables tested that failed due to rocking motions or twisting motions. The sequential shipping tests would probably show varying proportions of failures due to dropping, vibration, and rough handling. These might be sorted out using a Pareto chart. Then efforts could be made to improve the most frequently occurring causes. The cartridge drop and scrape test could also use p- or np-charts (see Chapter 13) to show results per sample of 100 repetitions of the test. The temperature tests would most likely use standard variables charts to measure whether test performance was within control limits, or not. Applying QFD in a Managed Care Organization 1. Although this example of QFD involved the design of a tangible items, it is more difficult to implement in a service context, as opposed to a pure manufacturing context, because
  • 9. Design for Quality and Product Excellence 5 both customer requirements and technical requirements are harder to quantify and assess that with tangible products. 2. The detailed calculations in the Importance of the hows row and Percentage of importance of the hows row used to arrive at these figures can be shown and verified on the spreadsheet labelled QIP-QFD Healthcare.xlsx. Note that some discrepancies involving incorrect multiplication, were found in part of the QFD “House of Quality.”

The rates of improvement, absolute weights, and percent improvements, based on the given values for “rate of importance” and “company now” and “plan” were validated. As in the original table, the “importance of hows” and “percent of importance of hows” turned out to be accurately calculated. Specific factors shown as the most important were “glossary terms” and “updates.”
  • 11. Design for Quality and Product Excellence 7 3. The lessons that can be learned and applied to other service organizations that seek to design or redesign their products and services include the facts that QFD provides for a systematic approach to linking the “voice of the customer” to operational requirements. By doing so, operating efficiencies can be realized and customer satisfaction can be enhanced. In addition, employee satisfaction often can be improved, as well, as found in the case. It must be recognized that time and effort is involved in gathering, sorting, and analyzing the characteristics and factors. Also, there is subjectivity in applying ratings and weights to variables. Hence, the results are not easy to predict and guarantees are limited. ANSWERS TO REVIEW QUESTIONS 1. Product design and development consists of six steps: • Idea Generation. New or redesigned product ideas should incorporate customer needs and expectations. • Preliminary Concept Development. In this phase, new ideas are studied for feasibility. • Product/Process Development. If an idea survives the concept stage, the actual design process begins by evaluating design alternatives and determining engineering specifications for all materials, components, and parts. This phase usually includes prototype testing, design reviews, and development, testing, and standardization of the manufacturing processes • Full-Scale Production. If no serious problems are found, the company releases the product to manufacturing or service delivery teams. • Market Introduction. The product is distributed to customers. • Market Evaluation. An ongoing product development process that relies on market evaluation and customer feedback to initiate continuous improvements. 2. Competitive pressures are forcing companies to reduce time to market, which means that the time for product development is also squeezed. The problems incurred in speeding up the process are well known. If done too hastily, the result will be the need to revise or scrap the design, cost increases or project over-runs, difficulty in manufacturing the product, early product failure in the field, customer dissatisfaction, and/or lawsuits due to product liability. One of them most significant impediments to rapid design is poor intra- organizational coordination. Reducing time to market can only be accomplished by process simplification, eliminating design changes, and improving product manufacturability. This requires involvement and cooperation of many functional groups to identify and solve design problems in order to reduce product development and introduction time. 3. Concurrent engineering is a process in which all major functions involved with bringing a product to market are continuously involved with product development from conception through sales. Such an approach not only helps achieve trouble-free introduction of products and services, but also results in improved quality, lower costs, and shorter product development cycles. Concurrent engineering involves multifunctional teams, usually consisting of 4 to 20 members and including every specialty in the company. The
  • 12. Design for Quality and Product Excellence 8 functions of such teams are to perform and coordinate the activities in the product development process simultaneously, rather than sequentially. Companies exploit concurrent engineering to achieve a competitive advantage. Typical benefits include 30 to 70 percent less development time, 65 to 90 percent fewer engineering changes, 20 to 90 percent less time to market, 200 to 600 percent improvement in quality, 20 to 110 percent improvement in white collar productivity, and 20 to 120 percent higher return on assets. 4. Design for Six Sigma (DFSS) uses a set of tools and methodologies in the product development process to ensure that goods and services will meet customer needs and achieve performance objectives, and that the processes used to make and deliver them achieve Six Sigma capability. DFSS consists of four principal activities: • Concept development, in which product functionality is determined based upon customer requirements, technological capabilities, and economic realities; • Design development, which focuses on product and process performance issues necessary to fulfill the product and service requirements in manufacturing or delivery; • Design optimization, which seeks to minimize the impact of variation in production and use, creating a “robust” design; and • Design verification, which ensures that the capability of the production system meets the appropriate sigma level 5. Concept development is the process of applying scientific, engineering, and business knowledge to produce a basic functional design that meets both customer needs and manufacturing or service delivery requirements. Developing new concepts requires innovation and creativity. Innovation involves the adoption of an idea, process, technology, product, or business model that is either new or new to its proposed application. The outcome of innovation is a discontinuous or breakthrough change and results in new and unique goods and services that delight customers and create competitive advantage. Innovations can be classified as: 1. An entirely new category of product; for example the iPod 2. First of its type on the market in a product category already in existence; for example, the DVD player. 3. A significant improvement in existing technology, such as the blu-ray player 4. A modest improvement to an existing product, such as the latest iPad. Creativity is seeing things in new or novel ways. In Japanese, the word creativity has a literal translation as “dangerous opportunity.” Many creativity tools, such as brainstorming and Brainwriting—a written form of brainstorming, are designed to help change the context in which one views a problem or opportunity, thereby leading to fresh perspectives. A creativity tool that finds extensive use in product design is TRIZ, which is a Russian acronym for the Theory of Inventive Problem Solving. TRIZ was developed by a Russian patent clerk who recognized that concepts of inventive problem solving could be taught, in order to foster creative problem solving.
  • 13. Design for Quality and Product Excellence 9 Concept development is an important tool for assuring quality because it provides a systematic process that leaves a strong audit trail back to the voice of the customer. This makes it difficult to challenge the results of skeptics and convert them. The process also helps to build consensus and gives design teams confidence in selling their concept to management. However, it takes a lot of discipline and patience. 6. Conceptual designs must be translated into measurable technical requirements and, subsequently, into detailed design specifications. Detailed design focuses on establishing technical requirements and specifications, which represent the transition from a designer’s concept to a producible design, while also ensuring that it can be produced economically, efficiently, and with high quality. 7. QFD benefits companies through improved communication and teamwork between all constituencies in the production process, such as between marketing and design, between design and manufacturing, and between purchasing and suppliers. Product objectives are better understood and interpreted during the production process. Use of QFD determines the causes of customer dissatisfaction, making it a useful tool for competitive analysis of product quality by top management. Productivity as well as quality improvements generally follow QFD. QFD reduces the time for new product development. QFD allows companies to simulate the effects of new design ideas and concepts. Companies can reduce product development time and bring new products into the market sooner, thus gaining competitive advantage. 8. In the QFD development process, a set of matrices is used to relate the voice of the customer to a product’s technical requirements, component requirements, process control plans, and manufacturing operations. The first matrix, called the House of Quality, provides the basis for the QFD concept. Building the House of Quality consists of six basic steps: * Identify customer requirements. * Identify technical requirements. * Relate the customer requirements to the technical requirements. * Conduct an evaluation of competing products or services * Evaluate technical requirements and develop targets. * Determine which technical requirements to deploy in the remainder of the production/delivery process. The first House of Quality in the QFD process provides marketing with an important tool to understand customer needs and gives top management strategic direction. Three other “houses of quality” are used to deploy the voice of the customer to (in a manufacturing setting) component parts characteristics, process plans, and quality control. The second house applies to subsystems and components. At this stage, target values representing the best values for fit, function, and appearance are determined. In manufacturing, most of
  • 14. Design for Quality and Product Excellence 10 the QFD activities represented by the first two houses of quality are performed by product development and engineering functions. In the last two stages, the planning activities involve supervisors and production line operators. In the third house, the process plan relates the component characteristics to key process operations, the transition from planning to execution. Key process operations are the basis for a control point. A control point forms the basis for a quality control plan delivering those critical characteristics that are crucial to achieving customer satisfaction. This is specified in the last house of quality. These are the things that must be measured and evaluated on a continuous basis to ensure that processes continue to meet the important customer requirements defined in the first House of Quality. 9. Manufacturing specifications consist of nominal dimensions and tolerances. Nominal refers to the ideal dimension or the target value that manufacturing seeks to meet; tolerance is the permissible variation, recognizing the difficulty of meeting a target consistently. Traditionally, tolerances are set by convention rather than scientifically. A designer might use the tolerances specified on previous designs or base a design decision on judgment from past experience. Setting inappropriate tolerances can be costly, since tolerance settings often fail to account for the impact of variation on product functionality, manufacturability, or economic consequences. The Taguchi loss function is a scientific approach to tolerance design. Taguchi assumed that losses can be approximated by a quadratic function so that larger deviations from target cause increasingly larger losses. 10. The Taguchi loss function is a useful concept for process design. Taguchi suggests that there is not strict cut-off point that divides good quality from poor quality. Rather, he assumed that losses can be approximated by a quadratic function so that larger deviations from target correspond to increasingly larger losses. For the case in which a specific target value, T, is determined to produce the optimum performance, and in which quality deteriorates as the actual value moves away from the target on either side (called “nominal is best”), the loss function is represented by L(x) = k(x - T)2 where x is any actual value of the quality characteristic and k is some constant. Thus, (x – T) represents the deviation from the target, and the loss increases by the square of the deviation. 11. Reliability is the probability that a product, piece of equipment, or system performs its intended function for a stated period of time under specified operating conditions. There are four key components of this definition, including probability, time, performance, and operating conditions. All of these have to be considered in a comprehensive definition of reliability. Probability allows comparison of different products and systems, time allows us to measure the length of life of the product, performance relates to the ability of the product to do what it was designed to do, and operating conditions specify to amount of usage and the environment in which the product is used. 12. A functional failure is one incurred at the start of the product's life due to defective materials, components, or work on the product. A reliability failure is one that is incurred after some period of use. For example, if a new TV set suffers a blown picture tube during
  • 15. Design for Quality and Product Excellence 11 the first week, it's a functional failure. There was obviously a defect in the manufacture of the tube. If the vertical hold feature of the set goes out (perhaps 3 days after the 1 year warranty is up), that is a reliability failure. It should reasonably be expected to last much longer than one year, but it didn't. 13. Reliability engineers distinguish between inherent reliability, which is the predicted reliability determined by the design of the product or process, and the achieved reliability, which is the actual reliability observed during use. Achieved reliability can be less than the inherent reliability due to the effects of the manufacturing process and the conditions of use. 14. Failure rate is defined as the number of failures per unit of time during a specified time period being considered. For example, if 15 MP-3 players were tested for 500 hours and there were two failures of the units, the failure rate would be: 2 / (15 x 500) = 1 / 3750 or 0.000267. 15. The product life characteristics curve, is the so-called "bath-tub curve" because of its shape. It is actually the failure rate curve, described above. Such curves can be used to understand the distinctive failure rate patterns of various designs and products, over time. 16. The reliability function represents the probability that an item will not fail within a certain period of time, T. It is directly related to the cumulative distribution function: F(T) = 1 - e-T , that yields the probability of failures. Since F(T) is the probability of failure, the reliability function, R(T) can be defined as the complement, e.g. probability of not failing: R(T) = 1 - (1 - e-T ) = e-T It can also be expressed using the mean time to failure (MTTF) value  as: R(T) = e-T/ 17. The reliability of series, parallel, and series parallel is relatively easy to compute, given the reliability of components in each system. For the series system, RS = R1R2R3. Thus reliabilities are multiplicative. For a parallel system, the relationships are a little more complex, since the units are designed to use redundant components, so that if one unit fails the system can continue to operate. The system reliability is computed as: RS = 1 - [(1 - R1)(1 - R2)(1 - Rn)] For series-parallel systems, the equivalent reliabilities of each parallel sub-system are calculated, successively, until there are no more parallel sub-systems. The system is then reduced to a serially equivalent system in which all component reliabilities can be multiplied to get the final reliability value. 18. Robust design refers to designing goods and services that are insensitive to variation in manufacturing processes and when consumers use them. Robust design is facilitated by
  • 16. Design for Quality and Product Excellence 12 design of experiments to identify optimal levels for nominal dimensions and other tools to minimize failures, reduce defects during the manufacturing process, facilitate assembly and disassembly (for both the manufacturer and the customer), and improve reliability. 19. The purpose of Design Failure Mode and Effects Analysis (DFMEA) is to identify all the ways in which a failure can occur, to estimate the effect and seriousness of the failure, and to recommend corrective design actions. A DFMEA usually consists of specifying the following information for each design element or function: Failure modes; effect of the failure on the customer; severity, likelihood of occurrence, and detection rating; potential causes of failure, and corrective actions or controls. A simple example of a DFMEA for an ordinary household light socket is provided in the chapter. 20. Fault Tree Analysis (FTA), sometimes called cause and effect tree analysis, is a method to describe combinations of conditions or events that can lead to a failure. In effect, it is a way to drill down and identify causes associated with failures and is a good complement to DFMEA. It is particularly useful for identifying failures that occur only as a result of multiple events occurring simultaneously. In other words FTA is a tool for carrying out the entire DFMEA process. 21. Product design can have a major impact on manufacturability. If careful thought and planning is not done by the designer (or design team), the end product can end up being difficult or impossible to build due to placement of components, methods for attachments, “impossible” tolerances, difficulties in attaching or fastening components and/or difficulties in getting the whole assembled “system” to work smoothly, even with the highest quality components. In addition time, materials, and other resources may be wasted unnecessarily due to a poor manufacturing design. The concept of Design for Manufacturability (DFM) is the process of designing a product so that it can be produced efficiently at the highest level of quality. Its goal is to improve quality, increase productivity, reduce lead time (time to market, as well as manufacturing time) and maintain flexibility to adapt to future market conditions. 22. Key design practices for high quality in manufacturing and assembly include: 1) analyze all design requirements to assess proper dimensions and tolerances, 2) determine process , 3) identify and evaluate possible manufacturing quality problems, 4) select manufacturing processes that minimize technical risks, and 5) evaluate processes under actual manufacturing conditions. 23. Social responsibilities in the design process include safety and environmental concerns, which have made Design for Environment (DFE) and Design for Disassembly important features of products. Legal and environmental issues are becoming critical in designing products and services, today. Product safety and its consequences, product liability, should be of primary concern because of the damage that hazardous designs can do to consumers of the product. Also, liability lawsuits can do major damage to the financial health of an organization, as well as its image and reputation in the marketplace. Records and
  • 17. Design for Quality and Product Excellence 13 documentation relating to the design process are the best defense against liability lawsuits. These would include records on prototype development, testing, and inspection results. Environmental issues involve questions of whether “environmentally friendly” designs (those that minimize damage to the environment in manufacture and product use) are being developed, what impacts will the design of the product have on the environment when it is scrapped, and how can consumers be given the most value for their money, while balancing the other two issues? The above questions can often be addressed by considering it as a “design for environment” concept (often combined with and “design for disassembly”). What is the best design for repairability/recylability? 24. Design for Excellence (DFX) is an emerging concept that includes many design-related initiatives such as concurrent engineering, design for manufacturability design for assembly, design for environment and other “design for” approaches. DFX objectives include higher functional performance, physical performance, user friendliness, reliability and durability, maintainability and serviceability, safety, compatibility and upgradeability, environmental friendliness, and psychological characteristics. DFX represents a total approach to product development and design involves the following activities: • Constantly thinking in terms of how one can design or manufacture products better, not just solving or preventing problems • Focusing on “things done right” rather than “things gone wrong” • Defining customer expectations and going beyond them, not just barely meeting them or just matching the competition • Optimizing desirable features or results, not just incorporating them • Minimizing the overall cost without compromising quality of function 25. The purpose of a design review is to stimulate discussion, raise questions, and generate new ideas and solutions to help designers anticipate problems before they occur. To facilitate product development, a design review is generally conducted in three major stages of the product development process: preliminary, intermediate, and final. The preliminary design review establishes early communication between marketing, engineering, manufacturing, and purchasing personnel and provides better coordination of their activities. It usually involves higher levels of management and concentrates on strategic issues in design that relate to customer requirements and thus the ultimate quality of the product. The preliminary design review evaluates such issues as the function of the product, conformance to customer’s needs, completeness of specifications, manufacturing costs, and liability issues. After the design is well established, an intermediate review takes place to study the design in greater detail to identify potential problems and suggest corrective action. Personnel at lower levels of the organization are more heavily involved at this stage. Finally, just before release to production, a final review is held. Materials lists, drawings, and other detailed design information are studied with the purpose of preventing costly changes after production setup.
  • 18. Design for Quality and Product Excellence 14 26. Methods of product testing for reliability include: life testing, accelerated life testing, environmental testing and vibration and shock testing. In life and accelerated life testing the product is tested until it fails. The latter speeds up the process by overstressing the item to hasten its eventual failure. Environmental and shock tests are performed to determine the product's ability to survive and operate under adverse conditions of heat, cold, or shock. SOLUTIONS TO PROBLEMS Note: Data sets for several problems in this chapter are available in the Excel workbook C07Data on the Student Companion Site for this chapter accompanying this text. Click on the appropriate worksheet tab as noted in the problem (e.g., Prob. 7-5) to access the data. 1. A hospital developed a design process consisting of the following steps: Plan, Design, Measure, Assess, and Improve. Below is a list of specific activities that comprise these five steps in random order. Place the activities in the most appropriate order within the correct step of the design process. Pilot or test design Submit proposal Define measures to assess design performance Implement design Identify potential solutions to reduce out of control conditions Develop business plan Disseminate improvements throughout the organization Monitor process performance Select the best solution to improve control Identify out of control conditions Propose new concept Create design to meet requirements Identify new improvement opportunities Monitor the new process design Implement the best solution to improve control Verify proposal alignment with strategic objectives Establish design team Identify causes of out of control conditions Analyze causes Identify and validate customer requirements Identify and evaluate best practices Answer 1. Although the terms might vary slightly, the following model captures the stages of the design process for the hospital:
  • 19. Design for Quality and Product Excellence 15 2. Newfonia, Inc., is working on a design for a new smartphone. Marketing staff conducted extensive surveys and focus groups with potential customers to determine the characteristics that the customers want and expect in a smartphone. Newfonia’s studies have identified the most important customer expectations as • Initial cost • Reliability • Ease of use • Features • Operating cost • Compactness Develop a set of technical requirements to incorporate into the design of a House of Quality relationship matrix to assess how well your requirements address these expectations. Refine your design as necessary, based upon the initial assessment. Answer 2. Analysis of customer responses for Newfonia’s proposed smartphone indicates the likelihood of several strong relationships between customer requirements and associated technical requirements of the design, such as value vs. price; features vs. compactness; and ease of use vs. features. Operating costs may possibly be distantly related to initial cost and features. Technical characteristics required to translate the “voice of the customer” into operational or engineering terms might be measures of purchase cost, operating programs (e.g., BranchOS, or other similar systems), number and type of features, weight, dimensions, battery life, cost of replacement batteries, and peripherals.
  • 20. Design for Quality and Product Excellence 16 3. Newfonia, Inc. (Problem 2), faces three major competitors in this market: Oldphonia, Simphonia, and Colliefonia. It found that potential consumers placed the highest importance on reliability (measured by such things as freedom from operating system crashes and battery life), followed by compactness (weight/bulkiness), followed by flexibility (features, ease of use, and types of program modules available). The operating cost was only occasionally noted as an important attribute in the surveys. Studies of their products yielded the information shown in the table in C07Data file for Prob.7-3on the Student Companion Site for this chapter. Results of the consumer panel ratings for these competitors are also shown in that spreadsheet. Using this information, modify and extend your House of Quality from Problem 1 and develop a deployment plan for the new smartphone. On what attributes should the company focus its marketing efforts? Answer 3. With the new data given for Newfonia’s potential customers, a partial House of Quality for the design of the smartphone can be built, as shown below. Note the strong relationships between customer requirements and associated technical requirements of the smartphone design. The inter-relationships of the roof are not shown (limitations of MSWord software), but these may be sketched in. For example, they would show a strong inter-relationship between size and weight.

It should build on the strength of the customer’s reliability concern, keeping battery life near 35 hours and use a proven operating program, such as BranchOS. Enough features (10) should be offered to be competitive. If Newfonia can design a high-value smartphone and sell it at an attractive price (say, $250 or less), it should be a very profitable undertaking. 4. Georgio’s Giant Gyros conducted consumer surveys and focus groups concerning a new giant gyro sandwich design, and the facility to sell it, and identified the most important customer expectations (not in any order of priority) as • Tasty, attractive, moderately healthy food • Speedy service • An easy-to-read menu board • Accurate order filling • Perceived value Develop only a set of technical requirements to incorporate into the design of the product and its delivery. Use a House of Quality relationship matrix to assess how well your requirements address these expectations. Include some technical dimensions that may be used to measure tasty, attractive, and “healthy” food; speedy service, acceptable menu boards, order accuracy, or perceived value. Refine your design as necessary based upon the initial assessment. Answer 4. Analysis of customer responses for Georgio’s Giant Gyros indicates that there are likely to be several strong relationships between customer requirements and associated technical requirements of the product and delivery system that Georgio designs (for example, a giant gyro product). Some strong relationships may be seen between moistness/flavor and trans- fat; calories/sodium/t-fat and nutrition; staffing levels and work procedures; kitchen capacity and facility layout; value and price; etc.. Note the three customer response categories that are unrelated to the design of the gyros -- order accuracy, speedy service, and menu board. These factors will probably require a separate analysis as part of a facility and process design, thus focusing on the product in one case, and the service delivery system in the other.

It found that consumers placed the highest importance on taste appeal (especially flavor) and order accuracy, followed by healthy food (measured by sodium content and calories), value, and service. The menu board was only casually noted as one of the least important attributes in the surveys. Georgio faces three major competitors in this market: Mario’s, Gyroking, and Antonio’s. Studies of their products yielded the information shown in the worksheet tab Prob.7-4 in the Excel file C07Data on the Student Companion Site for this chapter. Results of the consumer panel ratings for each of these competitors can also be found there (a 1–5 scale, with 5 being the best). Using this information, modify and extend your House of Quality from Problem 2 and develop a deployment plan for a new gyro. Assume that a separate study will be made on the physical facilities. On what attributes should the company focus its marketing efforts? Answer 5. With the new data given in C07Data.xlsx for Prob. 7-05 for Georgio's customers, a partial House of Quality for the design of the gyros can be built, as shown below. Note that the relationships between customer requirements (flavor, health, value) and associated technical requirements (% fat, calories, sodium, price) of the gyro design are strong. Note also that the focus here is on design of the product, not the service aspects of order accuracy and service. The inter-relationships of the roof are not shown, due to the limitations of MS Word® software. These may be sketched in. For example, they would show strong inter-relationship between % t-Fat and calories.

  • 25. Design for Quality and Product Excellence 21 ANSWER – CONTINUED 5. The Importance and Competitive Evaluation of customer requirements can be read from the survey results in the data tables in spreadsheet Prob07-05.xlsx that are provided, and placed under their respective columns Georgio’s Giant Gyros technical requirements must be placed on a more equal basis, which would best be shown as units/ounce, except for the percent fat value. These are shown below. Company Price/Oz. Calories/Oz.* Sodium/Oz.* Fat (%) * Georgio's $0.545 80.0 159.1 13 Kingyro $0.567 85.3 124.0 23 Antonio's $0.542 90.0 158.3 16 * Lower is better Thus, we can see from the competitive evaluation of technical characteristics and Georgio’s targets, that if Georgio’s is already low in price per ounce, as well as calories, and percent fat, its new product is leaner and healthier, as well as being cost effective. This analysis suggests that Georgio’s might consider increasing its size and flavor, which may indirectly affect its visual appeal, as well. However, Georgio has not targeted the size for an increase. At the same time, it should build on the strength of the nutrition trend by keeping the percent fat and sodium low. Georgio's has targeted sodium for a major reduction, from 159/oz. to 110/oz., and slightly reducing the number of calories per ounce, from 80 to 70, to be even more competitive. The facilities need some minor improvements, but their work procedures appear to be customer-pleasing. They merely need to hold the gains. If Georgio’s can design a flavorful, healthy, 5.5 oz. gyro and continue to sell it at the current attractive price or $3.00, it should be a very profitable undertaking. 6. A blueprint specification for the thickness of a refrigerator part at Refrigaria, Inc. is 0.300 ± 0.025 centimeters (cm). It costs $25 to scrap a part that is outside the specifications. Determine the Taguchi loss function for this situation. Answer 6.

In the production of Raphael Transformers, any output voltage that exceeds 120 ± 10 volts is unacceptable to the customer. Exceeding these limits results in an estimated loss of $200. However, the manufacturer can adjust the voltage in the plant by changing a resistor that costs $2.25. a. Determine the Taguchi loss function. b. Suppose the nominal specification is 120 volts. At what tolerance should the transformer be manufactured, assuming that the amount of loss is represented by the cost of the resistor?
  • 29. Design for Quality and Product Excellence 25 Answer 14. a) The Taguchi Loss function is: L(x) = k (x - T)2 200 = k (100)2 k = 0.5 So, L(x) = 0.5 (x-T)2 b) $2.25 = 0.5 (x-120)2 4.50 = (x - 120)2 (x - T)Tolerance = 50 . 4 = 2.12 volts 2.12 = x - 120  x = 122.12 15. At Elektroparts Manufacturers’ integrated circuit business, managers gathered data from a customer focus group and found that any output voltage that exceeds 55 ± 0.5 volts was unacceptable to the customer.
