Asset criticality

Rank your assets by what a failure really costs, so maintenance effort and spare parts go where they matter.

The problem

Not all assets are equal. Yet without a shared ranking, effort is often spread by feel: too much preventive work on secondary assets, not enough on the ones that stop the plant.

The same question applies to spare parts and to work order priorities. A clear criticality ranking gives maintenance, production and procurement a common rule.

Our approach

  1. Scoring grid defined with you: severity on safety, environment, production, quality and repair cost, and probability of failure.
  2. Scoring workshops with operations and maintenance, asset by asset, from the register.
  3. Calibration of the results so the ranking reflects the reality of the site.
  4. Using the ranking to steer maintenance strategies, spare parts stock and work order priorities.
