Problem Solving Process - The Terminology
Symptom – A quantifiable event or effect, experienced by a Customer
(internal external), that may indicate the existence of one or more problems.
Problem – A deviation from an expectation, standard, or status quo; a
perceived gap between the existing state and a desired state. In the context of
the 8D Problem Solving Process the cause(s) of the problem is not known.
Possible Cause – Any cause, identified through Process Mapping and C E
Matrix, Why-Why Diagram or Fishbone Diagram, that describes how an effect
may occur.
Most Likely Cause – A theory, based on available or collected data, that
best explains the problem description.
Root Cause – A verified cause that convincingly supports and explains
ALL facts available and thus accounts for the problem; verified passively and
actively, by making the problem come and go. Root causes are the
fundamental, underlying reasons for a problem, e.g. management policies,
product design, system design, process capabilities, technology constraints,
standard operating procedures and human errors.

“Describe the Problem” Key Activities

11 – 2/12/2013 – v1.0
C O N S U L T I N G
There are two steps to develop a good Problem Statement.
The first step is used to identify the object and the defect and develop the
initial Problem Statement.
The object and the defect are defined by asking “What is wrong with what?”
“What is wrong?” is the defect
The defect is an unwanted characteristic present in a product or
process – broken, missing, wrong, too short, …
“… with what?” is the object
The object is the name given to a specific product or process that
exhibits the defect
The Problem Statement (Step 1)

12 – 2/12/2013 – v1.0
C O N S U L T I N G
The 5 Why’s
Description: The 5 Why’s Analysis helps to identify the final problem
statement or in some cases even the root cause.
Step 1: Develop an initial problem statement of the specific problem to be
solved. Write it in the upper left corner of a piece of paper, flip chart or white
board.
Step 2: Ask “Why?” this problem does or could occur. Write the cause (object
defect) underneath the initial problem statement.
Step 3: The cause identified in Step 2 now becomes a new problem statement.
Repeat Step 2 and ask “Why?”, e.g. “Why would this situation occur?, again.
Step 4: Continue Step 2 and Step 3 until you cannot for certain answer the
question or reach an answer that is fundamental and actionable.

13 – 2/12/2013 – v1.0
C O N S U L T I N G
Once the initial problem statement (object defect) is established, the second step
is to use the “5 Why’s” and ask “Why would this situation occur?” or “Why is
that happening to that object?”
The objective of this step is to refine the initial problem statement to
determine the problem, rather than the symptom of the problem
focus efforts on a single problem with a single root cause
get as near as possible to the root cause using existing knowledge
information
check if the root cause of the problem is really unknown
If you are certain that you have found the root cause, then you can immediately go
to Phase 4 “Define and Verify Root Cause” and test your root cause theory.
However, if the cause is unknown and there is a need to find the root cause, then
the last object and defect with an unknown cause is the final Problem Statement.
The Problem Statement (Step 2)

14 – 2/12/2013 – v1.0
C O N S U L T I N G
Problem Statement - Example
What is the Problem Statement (Object Defect)?
WHY? → The tool was not in inventory.
WHY? → The Supplier did not deliver the replacement tools.
WHY? → The Supplier did not receive our Purchase Order on-time.
WHY? → We did not submit the Purchase Order on time.
WHY? → We did not have the “right” rework tool.
WHY? → We don’t know.

Process Flowchart
Most problem solving projects will require a process flowchart as the problem is
associated with a process that is failing. The team needs to understand how
that process works or at least is intended to work.
A Process Flowchart is a graphical process description of the work flow or
activities using standard symbols for each of the activities.
Different types of activities are described with standard symbols. The problem
areas in the process are often relatively easy to discover when assessing the
flowchart.
An ellipse shows the start and the end point of the process.
A box describes an activity or process step.
A diamond shows a decision making step.
An arrow shows the direction from one activity to another.

“Change-Induced” vs. “Day-One-Deviation”
Change
Performance SHOULD

When the process performance once met
the SHOULD and no longer does, then
you have a “Change-Induced” problem.
Performance ACTUAL

Day One
When a condition required for achieving the
SHOULD never existed, then you have a
“Day-One-Deviation” problem.

C O N S U L T I N G
The Problem Description
The Problem Description defines the boundaries of the problem, in terms of what it is
and what it is not but could be.
Scientific description of any event can be made by providing information on
What the problem is and what it is not but could be?
IS - The long brackets are missing
IS NOT - The short brackets are not missing (but could be)
Where the problem is and where it is not but could be?
IS - The order entry defects are in direct ship orders
IS NOT - The order entry defects are not in stock orders (but could be)
When the problem occurs and when it does not but could?
IS - The clips started breaking in early 2010
IS NOT – The clips did not break before early 2010 (but could have)
How big the problem is and how big it is not but could be?
IS - About 50% of the paychecks are incorrect
IS NOT – Not all paychecks are incorrect (but could be)

Identifying Possible Causes
To learn more about a specific problem and identify “all” possible
causes, the following tools are often very helpful and widely used.
Process Flowchart and Cause Effect Matrix or
Why – Why Diagram or
Fishbone Diagram
These tools work really great in a team environment to ensure that
everyone has a voice and every voice is being heard.
Select the Cause Effect Matrix, the Why-Why Diagram or the
Fishbone Diagram based on the problem you try to solve and/or your
personal or team’s preference.

23 – 2/12/2013 – v1.0
C O N S U L T I N G
Cause-and-Effect or Ishikawa Diagram is another way of looking at the possible
causes of a problem. It organizes large numbers of possible causes into pre-
defined categories, e.g. 4Ms 1 E or 4 Ps, or team-defined categories.

against the Problem Description and supporting data. Isolate and verify the
place in the process where the effect of the root cause could have been
detected and contained but was not (escape point).
Establish any additional data collection plans needed to learn more about
the problem and/or possible causes.

Comparative Analysis
The Comparative Analysis is the third part of the 8D Problem Solving
Process Worksheet.
The Comparative Analysis connects the facts from the Problem Description
(“IS – IS NOT” Matrix) with the analysis of possible causes using the Process
Flowchart and the CE Matrix or Why-Why Diagram or Fishbone Diagram.
Step 1: Compare each “IS” with its corresponding/contrasting “IS NOT”. List
any known distinctions and uncommon factors that could explain the “IS”
and “IS NOT”.
Ask: What is unique, odd, different, distinctive, unusual about the “IS”?
Consider the possible causes identified so far.
Step 2: List all known changes in distinctions and uncommon factors.
Ask: What has changed in, on, around or about this distinction and
uncommon factors?

Fishbone Diagram - Phase 2
In Phase 2 of the Fishbone Diagram, the team tries to reduce the large number of
possible causes to a short list of most likely causes, using the Problem Description,
Comparative Analysis, data analysis and the team’s combined process knowledge
and experience.
Remember, the root cause(s) convincingly supports and explains ALL facts available
and thus accounts for the problem. So, you need to ask yourself “If this would be
the root cause of the problem, would it explain the Problem Description?”

Root Cause Theory Testing
Step 1: Use the 8D Problem Solving Process Worksheet, supported by the CE
Matrix or Why-Why Diagram or Fishbone Diagram, to formulate Root Cause
Theories based on the identified most likely cause(s) of the problem.
Step 2: Enter a short description of a Root Cause Theory as header into the last
column of the 8D Problem Solving Process Worksheet.
Step 3: Assess the Root Cause Theory against each “IS” – “IS-NOT” statement.
Enter a “+” if the theory explains or does not conflict with the “IS”–“IS-NOT”
statement.
Enter a “-” if the theory conflicts with the “IS”–“IS-NOT” statement.
Enter a “?” if you are not sure and further investigation may be necessary.
The Root Cause(s) convincingly supports and explains ALL “IS”–“IS-NOT”
statements and thus accounts for the problem.

Root Cause Verification
Active Verification is a process where …
… the problem solver uses the variable thought to be the root cause to
make the effect come and go. Both coming and going are important tests
to confirm root causes.
Passive Verification is done by observation.
With passive verification, you look for the presence of the root cause
without changing anything. If you cannot prove the presence of the root
cause, then chances are great that this most likely cause is not the root
cause.
Step 1: Identify, document and perform a passive and/or active
root cause verification method.
Step 2: Continue with the 8D Problem Solving Process if the
passive and/or active root cause verification was successful.
Otherwise, develop and test additional Root Cause Theories.

Escape Point Identification
Step 1: Using the Process Flowchart, identify Escape Point(s)
for the verified root cause(s).
Step 2: Determine if Control Points were missing or ineffective
to detect the root cause of the problem at the escape point.
Control System: A control system is a system deployed to monitor the product
or process and ensure compliance to Customer requirements. It consists of
responsibilities, procedures and resources.
Control Point: A control point is a location within the control system where the
product or process is checked for compliance to certain specified requirements.
There may be multiple locations within a control system.
Escape Point: The escape point is the earliest location in the process, closest
to the root cause, where the problem could have been detected, but was not.

Out-of-Control-Action-Plans (OCAP)
The OCAP is a systematic and ideal problem-solving tool for process problems because it reacts to
out-of-control situations in real time.
OCAPs standardize the best problem-solving approaches from the most skilled and successful
problem solvers (experts/operators).
The OCAP also allows (and requires) off-line analysis of the terminators to continually improve OCAP
efficiency.
