Reactive Maintenance
Reactive maintenance is unplanned repair work performed in response to an unexpected asset failure or breakdown, typically more costly and disruptive than scheduled preventive or predictive approaches.
Reactive maintenance is maintenance work performed only after an asset has failed or broken down. It is the default approach in organisations without a structured maintenance programme, where equipment runs until something goes wrong and then a repair is arranged. Reactive maintenance may be deliberate (run-to-failure for non-critical items) or unplanned (breakdowns on assets that should have received preventive care).
Why it matters
When reactive maintenance dominates, organisations face higher repair costs, longer downtime, emergency parts procurement, and increased safety risk. Studies consistently show that reactive repairs cost two to five times more than the equivalent planned service. Tracking the ratio of reactive to planned work orders is a key indicator of maintenance programme maturity.
How MapTrack helps
MapTrack helps teams shift from reactive to planned maintenance by automating service schedules, sending overdue alerts, and providing reporting that shows the reactive-to-planned work order ratio over time.

Frequently asked questions
What is the difference between reactive and corrective maintenance?
Reactive maintenance specifically refers to unplanned work triggered by an unexpected failure. Corrective maintenance is the broader category of repair work performed after a fault is identified, which may include both reactive breakdowns and defects discovered during planned inspections. All reactive maintenance is corrective, but not all corrective maintenance is reactive.
What is a healthy reactive-to-planned maintenance ratio?
Best-practice maintenance programmes aim for no more than 20 per cent reactive work orders, with 80 per cent or more being planned (preventive, predictive, or condition-based). Many organisations starting their maintenance improvement journey find the ratio inverted, with 70 to 80 per cent reactive work. Tracking this ratio monthly shows whether the programme is maturing.
How can an organisation reduce reactive maintenance?
Start by analysing breakdown history to identify the assets and failure modes that generate the most reactive work. Implement preventive maintenance schedules for high-impact assets first, using OEM recommendations as a baseline. Ensure operators perform daily pre-start inspections to catch early warning signs. Over time, the preventive programme catches issues before they become failures.

Corrective Maintenance
Corrective maintenance refers to repair or restoration work carried out after a fault, defect, or failure has been identified in an asset. It may be triggered by an operator report, a failed inspection, or an unexpected breakdown. Corrective tasks range from minor adjustments to major overhauls, depending on the severity of the issue.
Preventive Maintenance
Preventive maintenance (PM) is a proactive maintenance strategy in which assets are serviced at predetermined time or usage intervals to reduce the likelihood of failure. Tasks may include inspections, lubrication, filter changes, calibrations, and component replacements. PM schedules are typically based on manufacturer recommendations, regulatory requirements, or historical failure data.
Downtime
Downtime is any period during which an asset is unavailable for its intended function. It can be planned (scheduled maintenance, shutdowns, inspections) or unplanned (breakdowns, failures, waiting for parts). Downtime is typically measured in hours and expressed as a percentage of total available time, providing a key indicator of asset availability.
