3. Module Objective: This module will provide information on issues related to the use of various data sources in an RCM analysis effort 1.Identify data sources that are useful for RCM analysis 2.Understand how data sources should be used and how they can be misused IntroductionIntroduction DATA CONSIDERATIONS

4. Data Sources Operators and Maintenance Manuals Operators and Maintenance Manuals Drawings Drawings Troubleshooting charts or diagrams Troubleshooting charts or diagrams Design Specifications Design Specifications Functional Block Diagrams Functional Block Diagrams CMMS data (any computerized equipment/ failure/maintenance data) CMMS data (any computerized equipment/ failure/maintenance data) Work orders (if not in a CMMS) Work orders (if not in a CMMS) Spare parts purchasing data Spare parts purchasing data Operator/Maintainer/Engineer/Vendor Tech Rep Knowledge Operator/Maintainer/Engineer/Vendor Tech Rep Knowledge Operator/Maintainer logs Operator/Maintainer logs Standards or regulatory requirements related to specific equipment Standards or regulatory requirements related to specific equipment Primary Sources DATA CONSIDERATIONS

5. CMMS Data Data Use and Misuse For discussion purposes: CMMS (3M) data is any automated or compiled data on failures, work orders, or maintenance actions. May use codes or keywords to categorize failures or maintenance actions May use codes or keywords to categorize failures or maintenance actions Sometime lacks specificity for detailed analysis Sometime lacks specificity for detailed analysis DATA CONSIDERATIONS

6. CMMS Data Data Use and Misuse One of the most common errors in RCM analysis is the misuse of CMMS Data. Focus on non-specific data versus SME knowledge and Focus on non-specific data versus SME knowledge and other specific sources can lead to superficial analysis other specific sources can lead to superficial analysis Full consequences of failure often not clear Full consequences of failure often not clear Results in inefficient analysis Results in inefficient analysis May force the analysis to too low a level May force the analysis to too low a level Tends to increase the number of insignificant failure modes considered Tends to increase the number of insignificant failure modes considered DATA CONSIDERATIONS

7. CMMS Data Data Use and Misuse Correct uses of CMMS data: Failure rate or probability of failure calculations Failure rate or probability of failure calculations Understanding of trends, maintenance task effectiveness, reliability characteristics, etc. Understanding of trends, maintenance task effectiveness, reliability characteristics, etc. Identifying/Prioritizing problem items for analysis Identifying/Prioritizing problem items for analysis As a check for completeness of identified failure modes As a check for completeness of identified failure modes Most common mistake: Using CMMS data as a primary means of determining failure modes Using CMMS data as a primary means of determining failure modes In most cases there is not enough detail to separate the important failures from the unimportant In most cases there is not enough detail to separate the important failures from the unimportant DATA CONSIDERATIONS

8. Review and Summary Use CMMS data to support other sources and not vice-versa Use CMMS data to support other sources and not vice-versa Establishing what data is available, how it will be used, and providing for access to it prior to beginning analysis is a key step to a successful analysis… Establishing what data is available, how it will be used, and providing for access to it prior to beginning analysis is a key step to a successful analysis… DATA CONSIDERATIONS
