1. Chapter 3 Understand the problem and the development of Engineering specification

2. 3.1 Introduction

7. 3.2 Step 1: identify the customs: Who are they

8. 3.3 Step 2: Determine the customer requirement
Production customer want
-Easy to manufacturing
3. Marketing/sales customer wan
-Easy to package, transport, is attractive, is suitable to display

10. 3.3.1 the Kano model of customer satisfaction

11. 3.3.2 Collection method for customers’ requirement
Three way to collect:
Observation,
Surveys,
Focus group

12. Step to help the design team develop useful data

15. Example questions including in the survey are:

17. 3.3.3 The type of Customers’ requirements

18. 3.3.4 The BikeE suspension requirement

20. 3.4 Step 3: Determine relative importance of the requirements: Who Versus What
Scale 1 to 10

21. 3.5 Step 4: Identify and evaluate the competition: How satisfied is the customer now

22. Rate the design on a scale of 1 to 5
The product does not meet the requirement at all.
The product meets the requirement slightly.
The product meets the requirement somewhat.
The product meets the requirement mostly.
The product meets the requirement completely.

24. 3.6 Step 5: Generate engineering specifications: How will the customers’ requirements be meet?

26. 3.7 Step 6: Relate customers’ requirements to engineering specifications: how to measure what?

27. 3.7 Step 6: Relate customers’ requirements to engineering specifications: how to measure what?

29. 3.7 Step 7: Set engineering targets: How much is good enough?

30. 3.8 Step 8: identify relationships between engineering requirements: How are the hows dependent on each other?
