Certified Reliability Engineer
Body Of Knowledge

The Certified Reliability Engineer (CRE) understands the principles of performance evaluation and prediction to improve product/systems safety, reliability, and

maintainability. 

This body of knowledge and applied technologies include, but are not limited to, design review and control; prediction, estimation, and apportionment

methodology; failure mode and effects analysis; the planning, operation, and analysis of reliability testing and field failures, including mathematical modeling;

understanding human factors in reliability; and the ability to develop and administer reliability information systems for failure analysis, design, and performance

improvement and reliability program management over the entire product life cycle.
