  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
