What is asset criticality analysis?
Asset criticality analysis ranks equipment by the consequence of its failure, combining factors such as production impact, safety, and cost. It tells a plant where to concentrate reliability effort, because a small share of assets usually drives most of the downtime risk.
Benchmark
| Benchmark | |
|---|---|
| Good | A current criticality ranking that actually drives the PM program and spares strategy. |
| Warning sign | No ranking, so maintenance effort is spread evenly instead of focused where failure hurts most. |
Why it matters
Reliability resources are always finite. Without criticality, plants spread preventive work and spares evenly and protect trivial assets as carefully as plant-stoppers. Criticality focuses the effort, which is what makes a reliability program affordable and effective.
How to improve it
Rank assets by failure consequence, then align the PM program, spares holding, and monitoring to the high-criticality items first.
