Purpose of Prioritization:
Classification #1: By Action
Listed below is a five tiered priority ranking scheme for physical conditions associated with individual assets:
Listed below is a 6 tiered priority ranking scheme for conditions associated with individual assets:
Listed below is a three tiered of mission criticality for facilities contemplated by the Mission Dependency Index:
Listed below is a four faceted priority scheme that plots the relationship between the urgency and importance of items on the urgency-importance matrix.
The following four-facet classification provides priority rankings for individual facilities/buildings within a portfolio based upon a Portfolio Condition-Priority Matrix (PCPM).
Classification #6: by Risk:
The next classification uses a risk matrix / criticality matrix to derive priority:
The next classification utilizes multivariate analysis to draw correlations between variables to establish priorities classes using a matrix tool.
Classification #8: by Purpose/Function/Driver
The next classification
Classification #9: by level
The next classification is based on the asset hierarchy.
Fig. The principles of ISO 55001 help to ensure that optimization is achieved through mindful balance and measured trade-offs between decision-making criteria.
Fig. The "currently critical" phase in the deterioration of an asset represented by the "red zone" on an asset degradation model.
Fig. Risk-based decision making is at the heart of asset management and this requires mindful consideration of the relationship between the probability of failure (PoF) and the consequences of failure (CoF). The complexities of these correlations can sometimes be captured on a risk matrix.
Fig. Prioritization organized by coloured location tags where "red" indicates high priority, "orange" is medium priority and "green" is relatively low priority.
Fig. Prioritization organized by seasonal bar chart where "red" indicates high priority and other colour indicate relatively lower priority tasks.
