The result of an RCM analysis is a set of The result of an RCM analysis is a set of recommendations for a series of discrete recommendations for a series of discrete maintenance tasks.maintenance tasks.

TASK PACKAGING is the process of combining TASK PACKAGING is the process of combining those discrete tasks into an efficient, effective, those discrete tasks into an efficient, effective, and executable maintenance program.and executable maintenance program.

• Concurrent tasks combined into a set of Concurrent tasks combined into a set of “work packages”“work packages”

• The objective is to minimize down-time and The objective is to minimize down-time and optimize use of resources optimize use of resources

The prior discussion centered on grouping tasks The prior discussion centered on grouping tasks as a result of task frequency. There are many as a result of task frequency. There are many other factors that may influence the decision to other factors that may influence the decision to group tasks:group tasks:

• Equipment locationEquipment location• Equipment ComplexityEquipment Complexity• Trades/Skills requiredTrades/Skills required• Availability of tools or parts requiredAvailability of tools or parts required• Down-timeDown-time• Elapsed Maintenance Time - Time Elapsed Maintenance Time - Time required to complete the tasksrequired to complete the tasks

There are some additional points to consider There are some additional points to consider when grouping tasks:when grouping tasks:

• Task compatibility Task compatibility • SequencingSequencing• Units conversionUnits conversion

Task GroupingTask GroupingTask GroupingTask Grouping

Task Compatibility Task Compatibility Task Compatibility Task Compatibility


Make sure that the tasks being packaged are Make sure that the tasks being packaged are compatible, for example:compatible, for example:

• One task requires equipment running while One task requires equipment running while another requires it to be disassembled… another requires it to be disassembled…


Task Sequencing Task Sequencing Task Sequencing Task Sequencing


Make sure that the tasks are sequenced in a Make sure that the tasks are sequenced in a way that is efficient and that does not impact way that is efficient and that does not impact the integrity of the tasks:the integrity of the tasks:

• Perform the calibration AFTER after the Perform the calibration AFTER after the inspection which requires disassembly… inspection which requires disassembly…


Units Conversion Units Conversion Units Conversion Units Conversion


• In building a package it may be necessary to In building a package it may be necessary to convert units of some tasks into the units of convert units of some tasks into the units of other tasks to organize them effectivelyother tasks to organize them effectively

• Be cautious when converting a task from one Be cautious when converting a task from one metric to another since the conversion is an metric to another since the conversion is an average and doesn’t consider variationaverage and doesn’t consider variation


Example of Example of conversionconversion



For example, results of an RCM Analysis indicatesFor example, results of an RCM Analysis indicatesthat is necessary to inspect a bushing in an that is necessary to inspect a bushing in an attachment fitting for wear every 500 operating attachment fitting for wear every 500 operating hourshours

If average equipment use were 50 hours per month,If average equipment use were 50 hours per month,simple arithmetic may suggest that inspecting for simple arithmetic may suggest that inspecting for wear every 10 months is acceptablewear every 10 months is acceptable
