Chapter 3 Understand the problem and the development of Engineering specification

3.1 Introduction

3.2 Step 1: identify the customs: Who are they

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

3.3.1 the Kano model of customer satisfaction

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

Step to help the design team develop useful data

Example questions including in the survey are:

3.3.3 The type of Customers’ requirements

3.3.4 The BikeE suspension requirement

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

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

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.

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

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

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

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

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