Corrective Maintenance
Repair work performed after a fault has been identified.
Definition
Corrective Maintenance is Repair work performed after a fault has been identified. In day-to-day operations, it matters when the team is deciding whether to prevent failure, fix a known issue, or respond to an immediate risk.
Operationally, it matters because the maintenance mix says a lot about how disciplined the operation is and how much downtime it absorbs. Planned work protects service quality, while reactive work usually arrives with more cost and stress.

Review Corrective Maintenance when the team needs to explain why a portfolio is absorbing too much reactive work.
Track Corrective Maintenance so operations can shift more labor into planned tasks before failure risk rises.
