Analysis & Validation (Quick Tip)
PM optimization has two key phases, Analysis and Validation. I am going to cover a few key principles for each phase in this blog tip. I see the same errors voiding the performance enhancing purpose of PM Optimization efforts so i want to pass on what i have learned to support others in their PM improvement endeavors.
During the analysis phase the key consideration is to carefully prepare, in advance, a detailed summary of actual PMs and tasks associated with them. Those tasks should be challenged by the most knowledgeable people against particular failure modes. If the task lacks meaning and the ability to prevent a potential failure, the team should decide if the task should be re-written, removed or worth changing is worth having a run to failure maintenance strategy in place. It is importantto understand the risk and consequences assumed with a run to failure strategy.
It is fundamental during the validation phase to take a 'walk around' the equipment to verify the newly created PM task. This includes checking that the PM task and maintenance frequencies are cohesive with the equipment reality. The worst result of a PM optimization process is create new PMs for tradespeople that lack practical sense at the time of execution. Planners are the first informal PM reviewers; they are a good resource to identify PM issues when they are doing the field assessment for PM work preparation. This is one of the key reasons for planner/scheduler's having good field knowledge.
