Question

2. What are the differences between product and service design? 3. Explain the meanings of benchmarking and reverse engineering. 4. Explain the meaning of design for manufacture (DFM) and give some examples. 5. Describe the stages of the product life cycle. What are demand characteristics at each stage?

Answer 1

Answer 2:

Product design	Service Design
Tangible	Intangible
Storable	Perishable
Control Quality with Data	Define Quality by Experience
Measure Output	Measure Outcome
Repeatable	Very Difficult to Repeat
Bonus
Can be Patiented	Very difficult to patient

Answer 3:

Benchmarking involves the usage of information gathered from world class companies in order to improve your company's performance. Reverse engineering is the study of an actual product by disassembling it to determine how it was created.

Answer 4:

Redesigned for manufacturability

Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology. DFM describes the process of designing or engineering a product in order to facilitate the manufacturing process in order to reduce its manufacturing costs. DFM will allow potential problems to be fixed in the design phase which is the least expensive place to address them.

Answer 5:

The main stages of the product life cycle are:

1. Research & development - researching and developing a product before it is made available for sale in the market
2. Introduction – launching the product into the market
3. Growth – when sales are increasing at their fastest rate
4. Maturity – sales are near their highest, but the rate of growth is slowing down, e.g. new competitors in market or saturation
5. Decline – final stage of the cycle, when sales begin to fall
