Chapter 9: Pedigree Analysis
A product pedigree describes its design and how it was built and shows that it was built in accordance with the drawings and other documentation defining the product configuration. Evaluating the pedigree of a failed product can help to rule in or rule out hypothesized failure causes. This chapter describes various areas that can be examined by the failure analysis team to assess the pedigree of the failed system. If the failure analysis team suspects product pedigree anomalies it should confirm conformance through independent means.
