Is the frequency of the task list appropriate, given the utilization of the unit? For example, a 24/7 unit sees a lot more use then a daytime-only one. If both have a 30-day PM frequency, one is over-PM'd or one is under-PM'd.
Are you performing PMs and still having failures on those systems? How can you include those failing systems into your PM task list for the future?
The answer to these questions should help make a difference in the failure rates, resulting in improved safety, lower cost of operation, reduced waste and happier customers.
