CMMS, EAM & Spare Parts Management calculator

Asset Criticality Score Calculator

Score asset criticality using consequence, failure likelihood, and detectability so maintenance and spares priorities align with risk. Use it with maintenance, reliability, spare-parts, storeroom, asset, labor, or cost data so the result supports a practical CMMS/EAM decision.

What this calculator does

  • Score asset criticality using consequence, failure likelihood, and detectability so maintenance and spares priorities align with risk.
  • a maintenance or asset-management team needs to rank equipment for PM strategy, critical spares, condition monitoring, and replacement planning for a asset criticality review
  • The result summarizes asset criticality score for the selected asset group, work order set, storeroom, spare-parts family, or maintenance reporting period.

Formula used

  • Asset Criticality Score risk score = asset consequence severity score × asset failure likelihood score × failure detectability weakness score
  • Use the same scoring scale across comparable assets, work orders, parts families, and maintenance risk reviews.

Inputs explained

  • asset consequence severity score: Score the consequence to safety, production, downtime, service, maintenance cost, inventory exposure, or asset lifecycle value.
  • asset failure likelihood score: Score likelihood using failure history, CMMS records, backlog age, supplier status, work order trends, or demand history.
  • failure detectability weakness score: Score weakness in current PMs, inspections, alerts, cycle counts, escalation reviews, supplier checks, or CMMS validation controls.

How to use the result

  • Use it when teams need a fast, documented basis to rank equipment for PM strategy, critical spares, condition monitoring, and replacement planning.
  • It remains an estimate when asset criticality, PM frequency, work order coding, labor availability, downtime cost, parts lead time, service level, inventory accuracy, or CMMS data quality differs from the assumptions entered.

Common questions

  • What is the asset criticality score calculator for? It helps reliability engineers, asset managers, maintenance managers, and equipment owners turn CMMS, EAM, work order, labor, downtime, spare-parts, or asset data into a practical estimate for a asset criticality review.
  • What data should I enter? Use current CMMS/EAM exports, work order history, PM schedules, technician labor records, storeroom transactions, supplier lead times, asset hierarchy data, downtime logs, and finance assumptions from the same site and reporting period.
  • When is the result only an estimate? It remains an estimate when asset criticality, PM frequency, work order coding, labor availability, downtime cost, parts lead time, service level, inventory accuracy, or CMMS data quality differs from the assumptions entered.
  • What decision can this support? Use the result to rank equipment for PM strategy, critical spares, condition monitoring, and replacement planning, then confirm budget, reliability, safety, and asset-management decisions with approved maintenance strategy, finance, and site operating requirements.
