Preventive Maintenance
Planned work done before a failure happens.
Definition
Preventive Maintenance is Planned work done before a failure happens. 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.
Use cases
Use Preventive Maintenance to decide whether the right answer is prevention, correction, or emergency response.
Review Preventive Maintenance when the team needs to explain why a portfolio is absorbing too much reactive work.
Track Preventive Maintenance so operations can shift more labor into planned tasks before failure risk rises.
