Term	Definition
Asset Prioritization Analysis	Asset prioritization analysis (also known as equipment risk prioritization) is an organized and methodical procedure for assessing the importance of assets within your organization. A prioritization analysis identifies the business risks posed by an asset’s failure in terms of safety, environmental impact, and operational and non-operational consequences. It takes into account the asset’s probability or rate of failure.
Asset Priority	A consequence priority number provides an indication of the relative priority of assets in the site. Priority numbers are calculated during an asset prioritization analysis. The priority number can be used to determine the order of work activities, and is used by the system to determine whether or not indicator alarms are shown on parent assets in the asset hierarchy. During the analysis, the priority number is determined by comparing the asset’s failure consequence scores to a set of rules. If the asset’s scores match a rule, the asset is assigned that rule’s priority number. The asset is always awarded the highest priority number that it matches.
Maintenance Task Analysis	Maintenance task analysis (MTA2) is APM’s unique strategy development methodology that enables the analysis team to quickly create and implement basic, technically-sound reliability programs. MTA2 is most effective when operational and maintenance knowledge about assets is well-documented and consistently used by employees. MTA2 provides an alternative to the resource-intensive RCM2 analysis, while still allowing you to identify the right work to improve performance across the plant. MTA2 methodology and tools allow the analysis team to: • Identify the assets to be analyzed • Identify the causes of asset failure • Recommend actions to prevent or mitigate failures
Operating Context	The operating context is the circumstances in which a physical asset or system is expected to operate.
RCM2	RCM2 is the reliability-centered maintenance process practiced by Bentley APM consultants. One of the features of RCM2 that distinguishes it from other interpretations of the RCM philosophy is that cross-functional groups of users and maintainers perform the analyses. After training, these analysis teams apply the process to their assets to produce robust and cost-effective asset reliability programs.
Relative Risk	Relative risk is one of the outputs from an asset prioritization analysis. It is the product of the probability of failure of an asset and the consequences of failure. Relative Risk = (Probability of Failure) x Sum (Consequence of Failure Scores)
Reliability Strategy Selection	Reliability strategy selection (RSS) analysis applies a set of criteria to an asset to determine the most appropriate plan for improving its reliability. The analysis team uses the Reliability Strategy Selection questionnaire to perform, document, and review analyses of system-level assets. Possible strategies are to implement (or continue) basic care, perform maintenance task analysis, perform RCM2 analysis, or escalate the asset risk to stakeholders for further consideration and action.
