Criticality Matrix Standards

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

Thus forming the required Criticality Matrix by multiplying the Severity Rating by the Probability Rating. An equipment criticality based on equipment failure and its resulting severity and probability occurrence.

The table below shows an example Criticality Matrix given the Risk to Personnel Injury.

Personnel Injury	Failure Probability Frequency
Severity	> 5 years	5 Years	1 Year	6 Months	< 14 days
Fatality	75	150	225	300	375
Invalidity	25	50	75	100	125
LTI (Loss Time Injury)	10	20	30	40	50
Medical Treatment	5	10	15	20	25
First Aid	1	2	3	4	5

The registration of the Criticality Matrix and where the Master resides is dependent on which application is used to run your company’s RCM Analysis. Either:

• IFS RCM Toolkit - The RCM Toolkit will define and be the Master of the Criticality Matrix, which in turn will be transferred/updated back in IFS through the IFS RCM Integration module. (IFS Cloud process used “Receive RCM Analysis”). Only the Criticality Matrix Standard identifier will be registered in IFS Cloud and be identical to the code used in the IFS RCM Toolkit.
• 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.
