1 The Design Specification Phase What Should be Addressed in the Product Design Specification

2 Overview of Design Process

3 Another View

4 Design Specification Phase What to Include Performance –temperature range –altitude –humidity –shock loading –corrosion resistance –noise levels –insects –user capability

5 Design Specification Phase What to Include Service Life –assessed against what? Maintenance –by whom? –how often? Target Production Cost –established at outset

6 Design Specification Phase What to Include Competition –competitive products –patents –papers formal evaluation Shipping Packaging

7 Design Specification Phase What to Include Quantity –market –production costs Manufacturing Facility –make it ourselves? –outsource? –what country?

8 Design Specification Phase What to Include Size –constraints? Weight Aesthetics –appearance –finish –what the customer sees!!!

9 Design Specification Phase What to Include Materials –any restrictions? –What do customers expect? Product Life Span –as a market entity Standards and Specifications –do any apply?

10 Design Specification Phase What to Include Ergonomics –user interface Customer –know what customer wants talk to them competitors trends

11 Design Specification Phase What to Include Quality and Reliability –determine up front manufacturing process distribution logistics –standards ISO 9000 UL ANSI/IEEE EEC (EU) –build in feedback to designer

12 Design Specification Phase What to Include Shelf Life (Storage) –very often overlooked Processes Time Scales –design time –tooling time –materials delivery times

13 Design Specification Phase What to Include Testing –why? –how? –when? Safety –OSHA –UL –labeling

14 Design Specification Phase What to Include Company Constraints –product history –manufacturing capability –financial –attitudes Market Constraints –know the market

15 Design Specification Phase What to Include Patents, Literature and Product Data –research all the data Political and Social Implications

16 Design Specification Phase What to Include References –“Product Design and development”, Ulrich and Eppinger, McGraw-Hill, Inc –“Total Design”, Stuart Pugh, Addison-Wesley Publishing Company, 1991 –Personal experience, 1958-present –http://www.rose- hulman.edu/~voltmer/EC460F00/pds.pdf
