One day I saw the following question on the LinkedIn:

“Should there be a way to measure the work identified by a PM that is not directly related to the PM task?” Would this be an additional measure of PM effectiveness or PM justification?”

So, I prepared an answer and posted it as a comment on the question and the reply came as follows: “This is exactly what I am looking for. Thank you!”

So, I decided to write this short article to share this benefit with you.

As we are performing PM/PdM (PPM) we should capture any sign of failures or any required corrective action and raise a “Corrective Work Order” to restore the asset to a condition in which it can perform its intended function, this is one of the main PPM program objectives.

If we keep doing PPM and don’t capture the failure symptoms or the required corrective action early enough to prevent the failures, then this is an indication of the ineffectiveness of this PPM program.

Corrective maintenance is the vehicle by which the effectiveness of the planned maintenance is monitored and measured.

That’s why, the Society for Maintenance and Reliability Professionals (SMRP) has developed a KPI (shown in Figure-1 below) states that 50% of corrective maintenance should come from “Structured Work”, i.e. Planned Maintenance (PPM).

If you know this, how can you then measure this KPI through your source of maintenance data, i.e. CMMS/EAM?

Here’s an already implemented solution that I offered to the colleague who asked the above-mentioned question:
Simply create a field in your work order screen and call it “Activity Type” where the proposed Activity Types are as shown in the table below:

The above created “Activity Type” field will be shown on the “Work Order” screen as in the example shown below:

This way you can capture corrective work that has been raised from different sources (mentioned in the above table) and accordingly measure the above-mentioned SMRP KPI.

I hope that this short article can help any of you.
