This configuration reinterprets the basic concept of failure-mode-and-effects to mean failure-mode-and reported-fault-signature. For each possible failure, this chart will list all tests within specified test sets that would fail if the given fault were to occur.

The eXpress Fault Signature Analysis Chart—by showing how each failure will manifest itself as a set of reported fault codes—allows the development of embedded diagnostics to be coordinated with diagnostic analysis efforts. As a result, fault signatures will be produced for each specific failure/cause pairing (to correctly represent the different fault signatures that will be reported when a failure results from different causes).
