Quality Cost Pitfalls Perfectionism in the numbers:

Lengthy debates can occur in some companies over the need for precision. This delay may cost the company the initiative to move forward with considerable total savings.

Other data pitfalls:

Presentation to managers should be done in a way that discussion is on the merits of improvement proposals and not on data validity.

Inclusion of non-quality costs:

The management group should decide on a definition of waste. That is, will only pure product quality waste be included? Implications of reducing quality costs to zero: A quality cost presentation should recognize that it may not be realistic or economically sound to reduce quality costs to zero.

Reducing quality costs but increasing total company costs:

It may be necessary to ensure that a reduction in quality costs will not increase total costs.

Understatement of quality Costs:

There are many ways to understate the costs of quality. One of the most common is to deal with quality costs only in excess of some normal standard. Inthe prevention approach, the emphasis should be to challenge whether the standard level can be improved.
