72
What are the 6 steps of doing Quality Function Development?
1. indentifying the customer(s) - list customer requirements (WHATs) 1.2. prioritizing the requirements 2. list technical desccriptors (HOWs) 3. develop a relationship matric between WHATs and HOWs 4. develop a relationship matrix between the technical descriptors 5. competitive assessments 6.1. setting engineering targets for design compute the relative weight 6.2. setting engineering targets for design 6.3. competition benchmarking
73
The goal is to develop a list of all the customer requirements (made up in the customer’s own words) that will affect the design. This should be accomplished with the whole design team, based on the results of customer surveys.
step 1. determining customer requirements
74
A weighting factor is generated for each requirement. The weighting factor will give the designer an idea of how much effort, time and money to invest in achieving each requirement.
step 1.2. prioritixing the requirements
75
The goal here is to develop a set of engineering requirements (design specifications) that are measurable for use in evaluating the proposed designs.
step 2. list technical descriptors (HOWs)
76
The last step is to determine the target values for engineering measurement.
step 6.2. setting engineering target for design
77
Measurements of the competition’s targets provide a basis for the _______.
development of targets for the new product
78
The best targets are those set for a ______.
specific value
79
Less precise, but still usable, are those targets set _____.
within a range
80
