Document Summary
Scamper tool how can we make x better by ? : substitute, combine, adapt, modify, put to other uses, eliminate, reverse/rearrange. 20 questions: q1-10, to break apart an existing process and challenge current assumptions, q11-20, to develop the next generation of improvement: Solution prioritization matrix: to weigh pros and cons, use consensus or a multivoting approach to narrow list of criteria to 10 or less, rank the criteria. Internal tolerances: internal test limits must be set tighter than customer"s specification limits to compensate for gauge error (offset by 3 times the gauge sigma) Failure modes and effects analysis (fmea: anticipating potential problems to take countermeasures to reduce/eliminate the risk, helps to pick a process during the define stage in dmaic or for ctq, 2 types: Design fmea to analyze products in the design stage. Process fmea to prevent process failures, assess risk, or to rank issues: what is needed to run an fmea:
