Full definition
Structured methodology to determine the optimum maintenance strategy for each asset based on analysis of functions, functional failures, failure modes, effects and consequences. Result: technically justified maintenance tasks (predictive, preventive, failure-finding or no scheduled maintenance). Standards: SAE JA1011 and JA1012. Developed by Nowlan and Heap for aviation (1978), adopted in process, nuclear and manufacturing industries. Reduces maintenance costs 15-40% with equal or greater reliability.
