ALD is one of the world leaders in conducting failure reporting, analysis and corrective actions (FRACAS) activities as well as developing and customizing FRACAS software tools. Back in 1984, the first full-scale failure data collection and reporting system for the big customers from aircraft and military industries contributed to ALD's solid reputation in the world reliability community. ALD established the failure data collection procedure, participated in actual data collecting and developed software for easy processing, analysis and reporting of accumulated data. Since then we have created, established and maintained FRACAS systems for dozens of satisfied customers widening our scope to telecommunication, semiconductors, software, chemical, and automotive industries.

Failure Data Collecting & Processing
Failure data collection and analysis are closely connected with all other reliability activities. Failure data collecting should start at an early stage of systems design and go on through the entire product life cycle. Both suppliers and users must perform the detailed tracking and analysis of equipment malfunctions and failures. ALD FRACAS specialists have established the failure data collection procedure defining the most critical data types for each phase of a product life cycle and ensuring the comprehensive processing leading to corrective action and preventive maintenance. Timely failure data collecting, recording and processing supported by the ALD software helps prevent failures from recurring as well as simplify and reduce maintenance tasks. Providing data for statistical analysis Failure Reporting, Analysis, and Corrective Action System (FRACAS) is a closed-loop feedback path in which the users work together with suppliers to collect, record, and analyze both hardware and software failures. The user captures predetermined types of data about all problems with a particular tool or software and submits such data to the relevant supplier. A Failure Review Board (FRB) at the supplier site analyzes all corrected 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.
Accurate trend analysis is one of the most valuable outcomes of timely and well-defined FRACAS. ALD FRACAS experts will perform the trend analysis by incorporating all existing historical reliability information: MTBF, MTTR, availability, preventive maintenance, etc. Analysis of deficiency patterns allows to define possible failure trends, and finally contributes to prevention of failures and unnecessary maintenance activities.
Field data collection should include:
Collecting field data as a part of a FRACAS process enhances product reliability, safety, quality and allows calculation and prediction of the following:
· Enhanced maintenance policy (RCM - reliability centered maintenance)
Customized workflow, data collection forms, user configurable output reports and much more.
