Stage 2—Project definition (QFD and new product development)

Phase 1: Innovation targets for subsystems

II - 1 Review charts from Segment I	A-1 Key customer demands, key quality characteristics A-2 Voice of the engineer, key quality characteristics B-1 Voice of the customer vs. voice of the engineer B-2 Cost targets for product B-3 Preliminary breakthrough targets C-1 System changes suggested by new technology C-2 System changes suggested by voice engineer C-3 System changes suggested by quality characteristics F-1 Cost reductions of functions and systems F-2 System changes based on process decision program chart and finite element method F-3 System changes based on factor analysis and reviewed dendogram
II - 2 A-4 Subsystem chart	Purpose Identify the key subsystems for improvement based on the ones that have strong relationship with key (top two or three) quality characteristics.
II - 3 B-4 Subsystem chart Key subsystems and key quality characteristics	Purpose / Comments Identify the key functions and key quality characteristics for each of the key (top two or three) subsystems and capability indices.

Phase 2 -: Innovation ideas for subsystems

II - 4 C-4 Subsystems vs. systems	Identify subsystems that relate to key systems. Identify targets for subsystem cost reduction.
II - 5 D-1 Fault tree analysis vs. customer demands	Prioritize reliability problems to work on based on customer demands.
II - 6 D-2 Fault tree analysis vs. functions	Prioritize reliability problems to work on based on voice engineer (functions).
II - 7 D-3 Fault tree analysis vs. quality characteristics	Prioritize reliability problems to work on based on critical quality characteristics.
II - 8 D-4 Subsystem failure modes vs. parts	Prioritize the development of subsystem product FMEAs based on an analysis of subsystem failure modes.
II - 9 E-1 New concepts for subsystems vs. customer demands	Preselect new subsystem concepts based on meeting voice of customer.
II - 10 E-2 New concepts for subsystems vs. voice of the engineer (functions)	Preselect new subsystem concepts based on meeting voice of engineer.
II - 11 E-3 New concepts for subsystem vs. critical quality characteristics	Preselect new subsystem concepts based on critical quality characteristics.
II - 12 E-4 New concepts for subsystems summary	Identify strengths and weaknesses of new concepts based on whether they are better or worse than existing product or best in class product when compared to customer demands, functions, and critical quality characteristics.

Phase 3 -: Innovation engineering for subsystems

II - 13

F-2 Reviewed Dendogram (see Figure D.3)

• Draw a diagram of potential subsystem and cost improvements based on data from steps II - 2 through II - 12.

II - 14 F-1, F-2, F-3	Develop engineering breakthroughs on systems and cost using value engineering, factor analysis, finite element method, process decision program chart, and other engineering breakthrough tools.
II - 15 B-2 Revise cost analysis based on engineering breakthroughs	Evaluate competitive cost position based on engineering breakthroughs. If satisfactory, go on to II-16. If not, review steps 13 and 14.
II - 16 A-4 Critical quality characteristics vs. new subsystems	Redo chart A-4 based on new subsystems developed in steps II-9 through II-14.
