Should Reactive Maintenance Be a Core Part of Your Strategy?

What Is Reactive Maintenance?

Reactive maintenance—also known as emergency or breakdown maintenance—is unplanned work performed after equipment fails. It typically involves replacing or repairing faulty parts to restore operation. Because failures occur unpredictably, this approach incurs high costs: unplanned downtime, overtime, expedited parts, and costly call‑outs.

While reactive maintenance can fit into a broader strategy, it should never catch you off‑guard. Reserve it for inexpensive, easily replaceable components or for assets located in remote locations where regular preventive visits are impractical—such as satellites. The goal is to limit the impact of unplanned failures on your business.

Despite its drawbacks, reactive maintenance still dominates North American facilities—about 55% of all maintenance tasks are reactive. The appeal is clear: it requires less staff, minimal planning, and a lower upfront budget. However, this short‑sighted cost‑saving can spiral into a vicious cycle of limited oversight, reduced control, and higher long‑term expenses.

Key Disadvantages of Reactive Maintenance

1. Budget Uncertainty. Failures are random; spare parts and labor may be unavailable, forcing premium prices for expedited shipping, travel, and after‑hours support.
2. Reduced Asset Longevity. Without routine care, systems never operate at peak efficiency, eroding the return on the initial capital investment.
3. Safety Risks. Under time pressure, technicians may skip safety protocols, increasing the likelihood of accidents.
4. Longer Turnaround. Diagnosing the fault, locating parts, and retrieving manuals can delay repairs, extending downtime.
5. Resource Drain. Field staff waste time chasing manuals and ordering components instead of focused maintenance.
6. Interruption of Planned Work. Emergency jobs often override scheduled tasks, causing cancellations or delays in preventive programs.
7. Collateral Damage. Minor issues can cascade into major system failures if not addressed comprehensively.
8. Hidden Costs. Unplanned downtime can delay orders, harm reputation, and reduce revenue.
9. Recurring Problems. Quick fixes that bypass root‑cause analysis may result in repeated breakdowns.
10. Higher Energy Bills. Poorly maintained equipment consumes more energy; simple greasing or filter changes can cut usage by up to 15%.

Emergency repairs can’t be eliminated entirely, but a strategic approach can mitigate their impact. Build redundancy with parallel production lines, maintain a full spare‑parts inventory, document clear emergency procedures, and train staff in rapid response techniques.

Finding the Right Balance

Industry best practice recommends an 80/20 split—80% preventive, 20% reactive. A robust Computerized Maintenance Management System (CMMS) can help you track, schedule, and reduce reactive interventions. For a deeper dive, read our blog on 3 Ways to Get Preventive Maintenance Under Control.
