DOD - Materiel Readiness and Maintenance Policy

DOD - CBM+ OSD Archive

CBM is a set of maintenance actions based on real-time or near-real time assessment of equipment condition which is obtained from embedded sensors and/or external tests & measurements taken by portable equipment.  

“The purpose of CBM strategy is to perform maintenance only when there is objective evidence of need, while ensuring safety, equipment reliability and reduction of total ownership cost.”
