Which strategy primarily focuses on fixing equipment after it has failed?

The strategy that primarily focuses on fixing equipment after it has failed is corrective maintenance. This approach involves responding to equipment breakdowns and performing repairs only once a failure has occurred. The objective is to restore the equipment to operational status after an unplanned incident.

Corrective maintenance is typically reactionary and does not schedule repairs ahead of time; instead, it addresses issues as they arise. This can often result in increased downtime and potentially higher costs, both in terms of lost productivity and emergency repair expenses.

In contrast, preventive maintenance aims to prevent failures by regularly scheduled inspections and services, while predictive maintenance utilizes data analysis to predict when maintenance should be performed, thereby allowing for planned interventions before failures occur. Proactive maintenance is focused on identifying potential issues and resolving them before they lead to equipment failure, aligning closely with the principles of preventive and predictive maintenance strategies.
