12. Misconceptions and Pitfalls
Not simultaneous design and production
Not a “quick fix” or “magic formula” for success
Does not require multiple tests of product until optimum design achieved.
Not to replace or be confused with inspection protocols and programs
pg. 371

13. Misconceptions and Pitfalls
Avoid using team members improperly
Avoid promises to meet unobtainable goals or schedules
Avoid tight tolerances or stringent requirements for one-pass design
Avoid changes in product during design phase
Avoid business as usual with “low-bid” vendors
Avoid automation before simplification
