A common starting point is preventive maintenance completion rate: the percentage of scheduled maintenance tasks completed within the intended timeframe. Hotels can also track overdue tasks, inspection findings, subsequent equipment failures, and the amount of corrective work discovered during preventive maintenance.

Completion rate alone does not establish whether the program is effective. A property could complete every scheduled task while continuing to experience recurring failures if the procedures themselves are inadequate.

Hotels should therefore evaluate both preventive maintenance activity and resulting equipment performance.
