For the past several years, the mission of the SMRP Best Practices Committee has been to standardize how maintenance and reliability professionals measure and calculate common (and not-so-common) key performance indicators, thereby establishing a sound foundation on which to build more robust best practices, and by which to measure and compare performance using consistent measuring systems. This is the first edition of what will be a living document provided by SMRP’s Body of Knowledge Directorate. The SMRP format for these definition documents is the best and most comprehensive in the world, and the process used to develop these definition documents is the most rigorous and thorough.

These metrics were created using a rigorous development process that included an initial draft, project manager review and edit, small team review and edit, full committee review and adoption, web review (public review and comment), harmonization (with other global metrics), validation (pilot implementation and verification), final edit and formatting, and final review and approval.

This authoritative compilation of thirty nine metrics definitions, along with the companion guideline documents and glossary, will provide you with reliable guidance on how to measure these indicators. It gives the maintenance and reliability professional the ability to: measure performance consistently; make valid comparisons; establish achievable goals and objectives; and set realistic expectations. The standardization of how we measure our maintenance and reliability practices forms the foundation for these goals. This compilation also very effectively sets the stage for the comprehensive and world-class benchmarking services being provided and managed by SMRP’s Benchmarking Committee, which uses these definitions in the SMRP Benchmarking survey questionnaire. The Best Practices Committee standardized these indicators; the Benchmarking Committee will identify performance thresholds for each.
