Incomplete specifications on new products are very common resulting in unreliable products and costly scope creeps and design changes. Designing out failures using lessons learned can result in very high reliability and significantly lower warranty costs. The quickest way to make use of the lessons learned is to learn from heuristics which are short statements based on wisdom from lessons learned over many products. The article covers examples to show how the heuristics were applied to successful products.
