5.8 Failure Reporting Analysis And Corrective Action System (Fracas)

So far we have seen how analyses like FMECA, FTA, HA can be carried out and how they can be used during the design phase. However these analyses are based on the previous experience with the design and similar products. Often we do come across several failures during the test and installation phase. To over come such failures observed during operation in the true environmental condition in the future design, it is necessary to compile the list of possible failures in a systematic and structured way. The failures form the wealth of data in designing better product. Questions such as what to improve? and what to design against? could be answered with this wealth of failure data.

A comprehensive failure reporting analysis and corrective action program is extremely important to the achievement of reliability in equipment. It is necessary to have a detailed program which assigns responsibilities to appropriate personnel to carry out this documentation of failure data. Early elimination of the causes of failure is a major contributor to reliability growth and attaining customer satisfaction after delivery of the product. It is easier to implement the corrective action if the failure causes are identified in the preliminary design stage. As the design matures the corrective actions become comparatively more difficult to implement. Cost and time play a major role in each corrective action. Therefore, it is important to employ FRACAS early in the development phase.

Products & Services
Reliability Software
Reliability software enables organizations to improve product safety and reliability by measuring performance against industry-wide standards.
Failure Mode and Effects Analysis (FMEA) Software
Failure mode and effects analysis (FMEA) software is used to track trends, generate statistics such as mean time between failure (MTBF), and determine the root causes of field failures (usually for products covered by a manufacturer’s warranty).
Safety and Health Services
Safety and health services perform testing, consulting and analytical activities related to worker protection, industrial hygiene, process accidents, facility dangers, occupational hazards, and consumer product safety.
Inspection Services
Inspection services examine products, parts, equipment, repairs, services, installations, and facilities to ensure quality, consistency, and condition, as well as conformance to required standards and/or procedures.
Safety Monitoring Systems
Safety monitoring systems monitor and collect information from machines and operations. If a safety fault occurs, they can signal an operator to take appropriate action, or perform the action automatically.
