Stock the parts that prevent long production interruptions.
Spare parts management balances inventory cost against downtime risk. Critical spares are selected based on failure probability, repair time, lead time, asset criticality, interchangeability, and the production impact of waiting for replacement parts.
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-APrioritize Long-Lead Critical Parts
A low-cost component can justify stocking when its failure would stop a high-value production asset for days or weeks.

Consumption history helps distinguish true critical spares from inventory that has never been needed.

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.
