Using an item in such a way that applied stresses are below rated values
The lowering of the rating of an item in one stress field to allow an increase… Read More
Reliability growth is the intentional positive improvement that is made in the reliability of a product or system as defects are detected, analyzed for root cause, and removed. The process of defect removal can be ad hoc, as they are discovered during design and development, a function of an informal test-analyze-and-fix process (TAAF), or it… Read More
