Hierarchy for Improving PM Tasks

1. ELIMINATE

This step involves complete elimination of maintenance tasks that do not add value. You can identify them by assessing the PM tasks against standard performance, IOM document, RBI report, and off course by involving relevant SMEs.

2. SUBSTITUTE

If first step doesn't work, apply substitution. This step involves identifying time-based maintenance tasks that could potentially be substituted with Condition-based regime.

3. EXTENSION

The next step to improve PM task is by extension of PM frequency. You can do this by firstly focusing on high frequency PM. To do that, you would require IOM document, RBI reports, FMEA data, and off course historical failure data in CMMS database.

4. REDUCE

This step involves taking away some irrelevant PM tasks from the maintenance task list. This requires a review of your task list and justifying which task needs removing or consolidating as a single task.

5. PLAN

That's the last resort if above steps fail. This depends entirely on the Planners and Schedulers. To achieve maximum productivity, all similar trade tasks have to be grouped together and covered within the same schedule for execution. Every PM task including breakdown that ties to a particular equipment should grouped together to increase productivity.
