At the conclusion of a systems failure analysis, the people involved should have a much more in-depth understanding of how the system is supposed to work. The analysis should help understand shortfalls in the design, production, testing, and use of the system. The failure analysis team will have identified other potential failure causes and actions required to preclude future failures. This is valuable knowledge, and it should not be set aside or ignored when the failure analysis team concludes its activities. This chapter is a brief account of the creation of failure analysis libraries, of process guidelines based on previous failure analyses, and of troubleshooting and repair guidelines. Also provided is a listing of the various steps that should be included in a failure analysis procedure.
