PEME uses a criticality methodology to match the Preventive Maintenance strategy for a production asset to the operational risk that failure would pose a manufacturer.
PEME’s Reliability lead, Stef Smith (pictured), has revised the Criticality Review Process that his team uses when completing Maintenance Improvement Projects.
The PEME Criticality Review process is a robust, user-friendly and proven method, to identify a criticality rating, for individual assets within a Plant, which is aligned with the PEME Asset Care Strategy. The Criticality Review process uses the PEME Criticality Model and this Model is populated in a Criticality Review Workshop.
The Criticality Review is split into 2 sections. The first section produces a ranked list of assets rated against Business Criticality factors whilst the second section produces a ranked list of assets rated against Reliability Criticality factors:
- An asset’s Business Criticality influences Asset Care decisions for that asset, e.g. intrusive Preventive Maintenance tasks are unlikely to be recommended for less critical assets. During the Criticality Review, any failure modes that have very high impact score against any of the Business Criticality factors are subjected to further analysis via a Failure Modes, Effects and Criticality Analysis (FMECA) to ensure an appropriate maintenance task(s) is defined to prevent the occurrence of the failure mode
- The Reliability Criticality can be used in conjunction with the Business Criticality when the order in which Reliability resource should be assigned to assets is important. This is especially relevant where limited Reliability and /or Maintenance resource is available
