System Risk Management Methodologies




Asset Prioritization

Decide which reliability strategy to deploy.


Maintenance Task Analysis

MTA is a Failure Mode & Effect Analysis (FMEA) methodology used to identify failure modes and determine recommended tasks for less critical physical assets.


Reliability-Centred Maintenance

RCM2 is the second generation of the maintenance technique that was developed  and used s in the most demanding maintenance arena -- civil aviation.



Our System Reliability Service comprises of 3 modules:

  • Asset Prioritization (AP) & Risk Profile Selection

  • Maintenance Task Analysis (MTA)

  • Reliability-Centred Maintenance (RCM2)


The First Step - Asset Prioritization & Risk Profile Selection  
Asset Prioritization and Risk Profile Selection are used to determine what approach to apply to each asset, whether to:

- Continue with existing maintenance program


- RCM2



The Next Step - Implement MTA or RCM2  

When is MTA applied ?

  • MTA is applied to assets based an evaluation of business risk
  • MTA is applied when developing a new maintenance program
  • MTA is applied when validating an existing maintenance program
  • MTA is applied when assessing a poorly performing non-critical asset
  • MTA is NOT applicable when asset failure can lead to serious injury, death, or breach of environmental standards, or if very little is known about the asset


When is RCM2 applied ?

RCM2 is recommended in preference to MTA:

  • where asset failure presents significant safety or environmental consequences
  • where asset failure represents serious operational consequences
  • where operational knowledge of the asset is weak
