摘要

Today, failure rates provide important information on product quality for both the product manufacturer as well as for the costumer. It is more and more industrial practice to dispute on product failure rates in business negotiations and to fix them by contract. If- later on - the declared failure rate turns out to be not achieved, the product provider may be obliged to cancel the damage committed to the costumer and possibly to pay fines. There are generally two different sources for obtaining product failure rates: field data analysis and failure rate prediction. While field data analysis is the preferred source as long as field data is available and representative, failure rate prediction is standardized, thus - in a certain sense - objective, and the only available method to obtain a failure rate if field data lacks.
