Product strategies and development processes should follow three key steps: 1) Identify market needs and segments 2) Match business goals to market needs 3) Add unique features or differentiation strategies Prototyping is an important design activity because it allows teams to: 1) Validate customer needs and opportunities with inexpensive, modifiable prototypes 2) Demonstrate that ideas are implementable and help teams understand products tactilely 3) Leverage technology to change directions adaptively without major consequences DFMA differs from traditional product development cycles by separately designing first for ease of manufacturing and then for ease of assembly, whereas traditional cycles design all at once for the whole process.

- 2. Question no: 1 How to improve product strategies and the management of the development process? Explain with general framework and explain relevant product structure concepts. Additionally, explain main relationship with the concepts and highlight major constraints and opportunities. Answer: General framework of product strategies: Three key points are involved in product strategy and these are: i. Market and needs-first product developers have to identify the market segment and then analyze the needs. ii. Business goals- match market needs with the business goals, identify the business capacity of creating products/services. iii. Key features, differentiators-to make the product diverse from competitors, add unique features or use differentiation strategy. General framework of management of the development process: The management of the development process is done by the following steps: i. Requirement analysis-key requisites will be identified while developing a product. ii. Design-it will be ensuring that the design must be robust. iii. Development-as soon as the design finalized, the development of product will be started. iv. Testing-then evaluation and refinement will be done. v. Deployment-in the end the product will be launch. Product structure concepts: Product structure is a hierarchical decomposition of a product, typically known as the bill of materials (BOM). Here is the example of general cycle. It is divided into 2 main categories and then these 2 are further sub divided into 7 components. 1. Assembled unit of cycle body a. Handle bar. b. Cycle frame. c. Seat. 2. Assembled unit of wheel. a. Wheel. b. Tire and tube. c. Pedal. d. Chain.
- 3. Major constraints and opportunities Constraints: i. The labor is not mentioned. ii. The time is missing. iii. The overhead cost is also not mentioned. Opportunities: i. It is a best source of cost estimation. ii. It is also best for control inventory. Question no: 2 How ‘Prototyping’ is a highly important activity in the design process? Explain with examples. Answer: 1. Validate the customer need and opportunity Test your idea early in a form that is easy and inexpensive to modify. 2. Demonstrate to you and your team that your idea is implementable. You won't know for sure about your product until you see it, that it really works. Even when it works, key members of your team may not understand it all until they can touch and feel it. 3. Leverage the technology to change directions as needed. A pre-production prototype will allow you to be adaptive without dire consequences. 4. Convince potential investors to take you seriously. If you have a validated a working prototype, investment risks are dramatically reduced. These days, if you don't have a proven prototype, investors probably won't even talk to you. 5. Early start on testing performance, materials, and quality. Work with the prototype will help you determine the best materials, to assure acceptable performance and durability. Example: The Al Umeed Rehabilitation Association (AURA) Karachi is using the prototype and suggests some additional functions. After re-designing they again tested the video game with 20 children with different disabilities, and claim a success rate of almost 78 percent. Now they partnered with the Rising Sun Institute, a special education organization for mentally and physically challenged children and helping them to providing entertainment and also aiming to improve their education as well.
- 4. Question no: 3 Differentiate between Design for manufacturing and assembly (DFMA) and Traditional Product Development Cycle. Answer: DFMA is the combination of two methodologies: Design for Manufacture, which means the design for ease of manufacture of the parts that will form a product. Design for Assembly, which means the design of the product for ease of assembly. Traditional Product Development Cycle consists of 4 steps: Define Design Develop Deploy Differentiate between DFMA and TPDC: In TPDC, the design has been done one time and for the whole process at a time while in DFMA, the design is separately propose first for manufacturing and then for assembly for the better results.
