PSW
When More Maintenance Isn’t the Answer

When equipment fails repeatedly, adding another inspection or increasing the frequency of a planned task can feel like the obvious response. But a fuller maintenance schedule won’t necessarily address the reason the equipment is failing.

The useful starting point is to understand the failure: what happened, how often it happens, what the consequences are and whether an existing task could realistically detect or prevent it.

  1. Identify the failure mode. Be specific about what is failing and how.
  2. Review the current task. Check whether it addresses that failure mode and happens at a useful interval.
  3. Look beyond the schedule. Operating conditions, installation, design and recurring defects may also need attention.
Make Each Task Earn Its Place

A maintenance review can reveal tasks that need to change, tasks that add little value and failures that need a different response altogether. The aim is to give the team a plan they can use, with a clear reason behind each activity.

“The right response to a failure depends on why it happened, not simply how often it happens.”

PSW helps teams examine maintenance plans against equipment performance and the consequences of failure. That can lead to a more focused strategy, with engineering time directed towards the work most likely to make a difference.
