A failure reporting, analysis, and corrective action system (FRACAS) is a system, sometimes carried out using software, that provides a process for reporting, classifying, analyzing failures, and planning corrective actions in response to those failures. It is typically used in an industrial environment to collect data, record and analyze
system
A system is a group of Interaction, interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment (systems), environment, is described by its boundaries, ...
failure
Failure is the state or condition of not meeting a desirable or intended objective (goal), objective, and may be viewed as the opposite of Success (concept), success. The criteria for failure depends on context, and may be relative to a parti ...
s. A FRACAS system may attempt to manage multiple failure reports and produces a history of failure and corrective actions.
FRACAS records the problems related to a product or process and their associated root causes and failure analyses to assist in identifying and implementing corrective actions.
The FRACAS method
MIL-HDBK-2155 at ASSIST
/ref> was developed by the US Govt. and first introduced for use by the US Navy and all department of defense agencies in 1985. The FRACAS process is a closed loop with the following steps:
# Failure Reporting (FR). The failures and the faults related to a system, an equipment, a software or a process are formally reported through a standard form (Defect Report, Failure Report).
# Analysis (A). Perform analysis in order to identify the root cause of failure.
# Corrective Actions (CA). Identify, implement and verify corrective actions to prevent further recurrence of the failure.
Common FRACAS outputs may include: Part Number, Part Name, OEM, Field MTBF
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation. MTBF can be calculated as the arithmetic mean (average) time between failures of a system ...
