5. What is the scope of the study?

5.1 Aspects of non-quality

We can distinguish two aspects related to the costs of non-quality:

• ">the first aspect is linked to the investments made to achieve the level of quality required. This is the price we have to pay to ensure an acceptable level of quality;

• ">the second aspect is the cost of doing things wrong, of not doing them right the first time.

The resulting cost is potentially twice as high as the investment needed to produce a compliant product.

Investment and structural choices are the responsibility of each company's management, and will not be the subject of this article.
