Define Criticality Matrix Standard
Explanation
A Criticality Matrix Standard defines the company’s required criticality matrix/matrixes' per Criticality Risk Element i.e. Personnel Safety, Environmental Spills, Production Losses etc. Where each Criticality Element will require:
- Failure Severity and their given ratings
- Failure Probability and their given ratings
- Failure Detectability and their given ratings
Thus, forming the required Criticality Matrix by multiplying the Severity Rating by the Probability Rating by the Detectability Rating. An equipment criticality based on equipment failure and its resulting severity, probability, and detectability occurrence.
The table below shows an example Criticality Matrix given the Risk of Personnel Injury.
The registration of the Criticality Matrix and where the Master resides is dependent on which application is used to run your company’s FMECA Analysis. Either:
IFS FMECA - IFS FMECA will be defined and need to connect to the Criticality Matrix. Then the ratings need to be given for different risk categories for each failure mode.
Third Party RCM Analysis Tool - In this scenario we will capture the Criticality Matrix Standard manually in IFS Cloud. Complete from Criticality Standard Identifier, Risk Category, Failure Severity and Failure Probability.
Application gives normalized values for ratings which will ranging between 0-100 taking the available maximum rating as 100 and normalize the rest of values accordingly. If ratings are not defined it won't be possible to use that for FMECA or Criticality Analysis.
