FRACAS | In-service Reliability module

Introduction

The FRACAS method was developed by the Department of Defence of the US. It is a closed loop system (implemented via software) that collects, analyses and records failures for specific items. It is intended to provide management visibility and control for reliability and maintainability improvement.

It is especially useful when applied in the first stages of a system usage, since the flexibility becomes more limited and expensive to implement as a design becomes firm.

The main procedures of the FRACAS system are:

1. Failure Reporting

2. Analysis of failures

3. Feedback of corrective action

The common FRACAS outputs are valuable reliability assessments, statistics and charts, and the main reliability parameters (MTBF, MTTR, MTBUR…).

When correctly applied (accurate failure documenting), FRACAS becomes an essential tool to apply positive corrective actions preventing further recurrence of the failures in the future.
