  1. Prioritizing Maintenance Work RIME & Reason By C. Paul Oberg, President EPAC Software Technologies, Inc.

  2. PRIORITY SYSTEM Why is a Priority System Necessary ? • Provides a means for evaluation of activities and backlog • Effective means of communicating importance • Provides an effective decision making tool

  3. PRIORITY SYSTEM Why is a Priority System Necessary ? • Organize needs in a hierarchical fashion based on an agreed upon set of criteria • Eliminates “squeaky wheel” • Helps optimize the use of resources

  4. PRIORITY SYSTEM To be an effective and lasting decision making tool, the Priority System must have the respect of: • Maintenance Customers • Maintenance Management • Maintenance Trades

  5. PRIORITY SYSTEM The priority system should be based on quantifiable, comprehensive and understandable criteria such as: • Facility/Equipment capacity utilization • Profitability of facility/equipment • Quality of “downstream” facility/equipment affected • Incremental maintenance costs if work is deferred

  6. PRIORITY SYSTEM The priority system should be based on quantifiable, comprehensive and understandable criteria such as: • Quality costs if work is deferred • Additional maintenance labor if work is deferred • Potential safety hazard if work is deferred

  7. PRIORITY SYSTEM Upon closer examination, we can separate criteria into two generic classifications: • Asset Type • Type of Work

  8. PRIORITY SYSTEM Ranking Index for Maintenance Expenditures (RIME) • Developed by Albert Ramond & Associates, Inc • Most widely used maintenance priority system • Two factor priority system comprised of: Asset Type Type of Work Priority

  9. PRIORITY SYSTEM Ranking Index for Maintenance Expenditures (RIME) Asset Type x Type of Work Priority Arithmetic: The product of these two factors give an index of the relative importance of the maintenance work to both facility/production and maintenance management. The process of establishing the relative importance of priority of a maintenance job is known as RIME.

  10. PRIORITY SYSTEM Who is best able to qualify these criteria ? • Asset Type ? • - MaintenanceUsers • Type of Work ? • - Maintenance Management

  11. Ranking Index of Maintenance Expenditures

  12. PRIORITY SYSTEM RESPONSIBILITIES Facility/Production Management must identify and classify: • Equipment • Buildings • Facilities • Systems Maintenance Management has the responsibility of defining and classifying: • Type of Work

  13. PRIORITY SYSTEM With all but one of his people on maintenance jobs, the maintenance manager has two jobs left to do. Which shall he/she assign the remaining person to and be confident that an appropriate decision has been made? JOB A Rebuild a spare fan motor JOB BConduct Preventive Maintenance on a pick-up truck which is infrequently used

  14. PRIORITY SYSTEM RIME Calculation Asset Type Value x Type of Work Value = RIME 49 7 X 7 JOB A 6 9 54 JOB B X

  15. MAINTENANCE ANALYSIS Trend Analysis provides insight into… • uAre we putting the emphasis on the right jobs • based on departmental backlog and completed job history ? • uShould our staffing be redistributed from Area 1 • to Area 2 based on comparative backlog, size and • importance ? • uAre our preventive and corrective maintenance programs effective based on the trend of backlog importance ?

  16. MAINTENANCE ANALYSIS Trend Analysis provides insight into….. uAre we doing more or less important work than previous ? uShould overtime/ outside resources be adjusted based upon size and importance of backlog ? uShould department “A” focus more on preventive and/ or corrective maintenance based on importance of the jobs requested and completed ?

  17. MAINTENANCE ANALYSIS Using RIME to Evaluate Maintenance Trends • Backlog trends • Work Completed Trends • Level of Service

  18. MAINTENANCE ANALYSIS AverageRIME:Weighted Average base upon trade hours: RIME X HOURS = RIME HOURS 42 X 24 = 1008 JOB: A JOB: B JOB: C JOB: D 54 X 18 = 972 90 X 34 = 3060 72 X 18 = 1296 TOTALS: 94 6336 Average RIME = Total RIME Hours = 6336 = 67.4 Total Hours 94

  19. MAINTENANCE ANALYSIS Current Level Trade Analysis Level 1 Low Average RIME 0 to 40 Level 2 Moderate Average RIME 40 to 80 Level 3 High Average RIME 80 to 100

  20. MAINTENANCE ANALYSIS Current Level Trends Analysis

  21. MAINTENANCE ANALYSIS JOBS COMPLETED AVERAGE RIME Level Slope Interpretation and Possible Action HIGHUPDangerously high level of emergency and breakdown occuring. Increased maintenance manpower levels with emphasis on PM/CM during non-operating periods should be considered until the level has been reduced to moderate. The level of emergency and breakdown work is too high. Continued emphasis on PM/CM and increased manpower levels should be considered. HIGH FLAT OR DOWN

  22. MAINTENANCE ANALYSIS JOBS COMPLETED AVERAGE RIME Level Slope Interpretation and Possible Action Moderate UPThe Overall level indicated a satisfactory mix of work, while the upward slope indicates an increase in emergency or preventive main- tenance jobs. This cannot be determined without specific data. Overtime should be used to control the level of backlog hours. Moderate FLAT Current mix of work is good. With the slope being flat, the only concern is the size of the backlog.

  23. MAINTENANCE ANALYSIS JOBS COMPLETED AVERAGE RIME Level Slope Interpretation and Possible Action Moderate DOWN The Current level indicates a good mix of work. However, the downward slope indicated less meaningful work is being requested and worked. This situation will lead to a potential manpower reduction position.

  24. MAINTENANCE ANALYSIS JOBS COMPLETED AVERAGE RIME Level Slope Interpretation and Possible Action LOW UP, FLAT The Current level indicates an improper mix of low priority jobs being worked. This condition will exist for one or both of two reasons: 1. Improper scheduling of priority work. Check the backlog trend for level and slope. 2. An excessive manpower level is capable of using all work request regardless of priority level. Review manpower level for possible reduction. s s

  25. MAINTENANCE ANALYSIS LONG RANGE TREND ANALYSIS The jobs completed average RIME line should be higher than the backlog average RIME line. The slope of the backlog line should be either flat or negative relative to the slope of the jobcompleted line. Meaning…………..

  26. MAINTENANCE ANALYSIS LONG RANGE TREND ANALYSIS s…..The higher priority work is being scheduled and completed first. The jobs being added to the backlog are of equal or lower average RIME than jobs being completed. Continuation of these conditions will lead to an operating position where maintenance requirements will be excessive.
