The maintenance strategy that emphasizes emergency repairs, particularly when incidents occur infrequently or when there is little to no preventive maintenance performed, is reactive maintenance. This approach entails addressing equipment failures or system malfunctions only after they happen, leading to immediate repairs to restore functionality.

Reactive maintenance is often seen as a more cost-effective approach in situations where equipment is reliable and has a low failure rate. However, it can lead to unexpected downtimes and can be quite disruptive when failures do occur. Focusing on this strategy often results in a lack of planning for maintenance activities, as the response is driven by the consequences of unanticipated failures rather than a structured maintenance schedule.

In contrast, preventive and proactive maintenance strategies are designed to minimize the need for such emergency interventions by regularly checking and servicing equipment, while predictive maintenance aims at anticipating failures before they occur by analyzing equipment performance data.
