Keep critical equipment available when production needs it.
Equipment reliability is the ability of a machine or system to perform its required function consistently over time. Reliability improvement combines failure history, maintenance strategy, condition monitoring, spare parts, repairability, operating conditions, and root-cause action.
Control recurring maintenance work with clear standards and feedback.
Intervals, equipment condition, work history, parts, measurement, and production impact should stay connected so maintenance decisions remain practical.
Make maintenance work easier to execute and easier to verify.
Strong maintenance systems define what should be done, when it should be done, what evidence is required, and how the result changes future planning.
CRIT-AFocus on Critical Assets
Reliability effort should be concentrated where failure creates the greatest production, quality, or recovery risk.

The same recurring fault often deserves more attention than unrelated one-off events.

Access, documentation, standard components, diagnostics, and spare parts can reduce the production impact when failure does occur.

Reliability improvement should appear in longer failure intervals, shorter recovery, less downtime, and more stable output.

These diagrams separate trend information from the time consumed by inspection, service, repair, and verification.
Condition trend.
Use trend data to see whether equipment health is improving, stable, or moving toward failure.
Work allocation.
Separate inspection, planned service, repair, and verification to understand where maintenance resources are being consumed.
Relevant maintenance and measurement resources.
