What is CMMS (Computerized Maintenance Management System)?

A CMMS is software that centralises maintenance work: requests, work orders, preventive maintenance schedules, asset records, spare parts and reporting.

Maintenance teams use a CMMS to move from reactive repairs to planned work. Technicians receive and close work orders on mobile, preventive tasks are generated automatically by calendar or meter readings, and every action builds an asset history used for audits and reliability analysis.

Common metrics tracked in a CMMS include MTTR, MTBF, PM compliance and the ratio of planned to unplanned work.
