© 1999 John W. NazemetzSlide 3 Computer Integrated Manufacturing Systems Assignment (1) Assume you are a consulting firm which develops concurrent engineering processes for client companies. Using the QFD methodology of Sullivan, develop a series of matrices for your product (i.e., develop Figures comparable to Fig 4.5, 4.6, 4.7, 4.9 (hypothesize competitors), 4.13). Note: all of these figures are cumulative so one matrix which contains all of the information will suffice.Assume you are a consulting firm which develops concurrent engineering processes for client companies.

NazemetzSlide 4 Computer Integrated Manufacturing Systems Assignment (Hint) Hint: you may wish/benefit from establishing a (multi-level) hierarchical grouping of requirements, control characteristics, etc.-- this will help you in dealing with your concepts as abstract groups -- e.g., you may wish to use the abstract groupings Design, Process Planning, … and then use these to organize your thinking with respect to customer requirements, control characteristics, etc.Hint: you may wish/benefit from establishing a (multi-level) hierarchical grouping of requirements, control characteristics, etc.-- this will help you in dealing with your concepts as abstract groups -- e.g., you may wish to use the abstract groupings Design, Process Planning, … and then use these to organize your thinking with respect to customer requirements, control characteristics, etc.
