The purpose of this section is to clarify the basic concepts of the FRACAS world:

FRACAS Sematech

FRACAS by Sematech - describes the stages that compose the close-loop FRACAS proces:

"Failure Reporting, Analysis, and Corrective Action System (FRACAS) is a closed-loop feedback path in which the user and the supplier work together to collect, record, and analyze failures of both hardware and software data sets. The user captures predetermined types of data about all problems with a particular tool or software and submits the data to that supplier. A Failure Review Board (FRB) at the supplier site analyzes the failures, considering such factors as time, money, and engineering personnel. The resulting analysis identifies corrective actions that should be implemented and verified to prevent failures from recurring …"

FRACAS by RAC (Reliability Analysis Center) - Describes FRACAS process benefits :

"Up-front design and reverse engineering of existing products and systems are important tools in the solution of complex reliability problems. A failure reporting and corrective action system (FRACAS) is defined, and should be implemented, as a closed-loop process for identifying and tracking root failure causes, and subsequently determining, implementing and verifying an effective corrective action to eliminate their reoccurrence…"

FRACAS by Department of Defense - MIL-STD-2155 (AS)

" A disciplined and aggressive closed loop Failure Reporting , Analysis, and Corrective Action System (FRACAS) is considered an essential element in the early and sustained achievement of the reliability and maintainability potential Inherent in military systems, equipment, and associated software. The essence of a closed loop FRACAS is that failures and faults of both hardware and software are formally reported, analysis is performed to the extent that the failure cause is understood, and positive corrective actions are identified, implemented, and verified to prevent further recurrence of the failure… "
