Asset Criticality Ranking A Best Practice Overview Asset Reliability Systems & Technology Strategy & Process Asset Criticality Ranking Overview What is Asset Criticality Ranking (ACR)? A tool used to evaluate how asset failures impact organizational performance Provides reliability leaders a detailed profile of characteristics that makes each asset critical Provides focus to ensure that reliability improvements are made based on calculated risk rather than perception: Safety and Environmental Impact Operational Throughput Maintenance Costs Utilization Rate Allows for the systematic ranking of assets for prioritization of all efforts 22 1
Asset Criticality Ranking Overview Benefits to ACR Primary mechanism needed to prioritize improvement activities when time and resource availability are limited This prioritization should be applied to Continuous Improvement efforts PM Optimization (PM and PdM Development) Bill of Material Development (to include Critical Spare Parts) Capital Investments This prioritization should also be applied to Daily Management of the CMMS Workflow Process Planning Scheduling Material Procurement 33 Asset Criticality Ranking Overview Critical Success s The ACR process is made up of two phases The first phase is the initial analysis which requires crossfunctional input from Operations, Maintenance, Engineering, Quality, and EH&S This cross functional analysis is required to ensure an accurate criticality ranking as well as gain buy in and overcome perceptions of criticality The second phase is evergreen, meaning that the criticality ranking process must be maintained and reevaluated throughout the asset s lifecycle (approximately every 12 18 months or as triggered) This is done to determine when risk has been mitigated and the significance of each asset has changed 44 2
Asset Criticality Ranking Overview ACR Strategy Development 1. Determine the Components for ACR Asset Business Impact / Asset Reliability Impact 2. Determine the s for each Component Operational Throughput / Utilization / Quality / Detection Risk / etc. 3. Determine the and Scoring for each 4. Determine the Weighting for each 5. Determine the Scoring Calculation for each Component 6. Determine the Scoring Calculation for ACR Utilize Range Scaling if needed 7. Determine ACR Score groupings for bulk analysis Classification / Percentile / Quartile 55 ACR Framework Breakdown Asset Criticality Ranking Component Component Score 1 A B C D E F G H I 2 3 4 Component Score = A * B * C * D * E Component Score = F * G * H * I ACR Score = Component Score + Component Score 66 3

ACR Classification Classifying (or Grouping) your Assets based on ACR is a primary mechanism used for prioritization Beyond basic Classification as shown above, your Assets can be sorted by ACR Percentile and ACR Quartile 111 ACR Execution Process Map 1212 6
Applying Asset Criticality Ranking to the CMMS Work Order Priority & Work Order Criticality Work Order Priority combined with Asset Criticality Ranking allows for a quick and efficient distribution of Work Orders using WO Criticality. WO Priority + ACR = WO Criticality 1313 Applying Asset Criticality Ranking to the CMMS ACR for Planning Utilize ACR to rank your Assets, driving priority for Work Orders that require PLANNING in the CMMS. 1414 7
Applying Asset Criticality Ranking to the CMMS ACR for Scheduling Also utilize ACR to prioritize Work Orders for SCHEDULING in the CMMS. 1515 Applying Asset Criticality Ranking to the CMMS ACR for PM Optimization Input your developed PM s and associated Job Plans from your ACR based PM Optimization effort into the CMMS. 1616 8
