Prepare the work before production is taken offline.
Maintenance planning defines the job scope, labor, parts, tools, access, permits, isolation, expected duration, testing, and restart steps before the equipment is removed from service.
Use equipment condition, risk, and production priority to guide maintenance work.
Good maintenance strategy connects machine condition, failure history, planned work, critical spares, and production schedules instead of treating every asset the same.
Prevent avoidable downtime without over-maintaining equipment.
Maintenance effort should be proportional to asset criticality, failure behavior, detection capability, repair risk, spare-parts exposure, and the production consequences of failure.
CRIT-ADefine the Job Before Shutdown
Clear scope prevents technicians from discovering missing parts, tools, drawings, or access requirements after production has already stopped.

Maintenance should be timed around demand, changeovers, product schedules, and constraint availability whenever possible.
Related Guide →CRIT-CPlan Verification
Repairs should include a defined test and restart process so the asset returns to production in a controlled condition.

Findings, replaced parts, failure modes, and follow-up work should update future maintenance plans.

These diagrams show condition trend and the way maintenance time is divided between inspection, planned work, repair, and verification.
Condition trend.
Monitor change over time so maintenance can respond before the condition becomes a production failure.
Maintenance allocation.
Separate inspection, planned service, repair, and restart work to understand where maintenance time is being consumed.
Relevant maintenance and equipment resources.
