Planned Maintenance Percentage (PMP)
Planned maintenance percentage is the share of maintenance labour hours spent on planned, scheduled work versus reactive emergency work. A high PMP, often targeted around 80–90%, signals a proactive, well-controlled maintenance organisation.
Planned work is identified, estimated, kitted and scheduled in advance; reactive work is unplanned response to breakdowns. Because planned work is far more efficient — typically a fraction of the cost and time of equivalent reactive work — the planned maintenance percentage is a core indicator of maintenance maturity. Raising it depends on effective planning and scheduling, a healthy backlog and the early warning that condition monitoring provides.
