There are many different theories and practices available in modern physical asset management. One of these techniques is Failure Mode, Effects, and Criticality Analysis (also known as FMECA) which is an extension of FMEA. FMECA is rigorous practice for assessing the design of products and operational and maintenance procedures with the goal of reducing the risk of product or system failure.

The core of FMECA is that the causes of failure (failure modes) result in undesirable effects. These may include reduced business effectiveness such as production loss, inefficiency, failure to achieve desired mission etc.

Reliability Centered Maintenance

A widely used maintenance decision-making technique is RCM, or Reliability Centered Maintenance. With RCM, the processes used to correct or prevent the Failure Modes focus on reducing, eliminating or otherwise mitigating the consequences of the failure mode, not necessary preventing the failure mode only. This is because the consequences of a failure matter more to the business than the failure itself.

In addition, RCM2 involves identifying maintenance requirements that will preserve the functions an asset performs. For this reason, it is important when applying RCM2 to understand the way that groups of assets work together. Maintenance policies can then be developed to ensure that the asset will continue to meet the requirements of the business rather than considering the asset in isolation.
