We have data. Often an abundance of data concerning equipment failures. Failures per month or MTBF type measures do not reveal sufficient insights to understand the pattern of failures.

We need to know if the rate of failures is increasing or not if the maintenance program is helping or hurting the equipment long term. We need to understand the pattern of failures to properly align our maintenance strategy.

Let's explore two ways to use the time to failure data you already have available (or should have). For repairable items the mean cumulative function and associated plots provide you estimate the effectiveness of your repairs. Are repairs restoring the system to good-as-new' condition or bad-as-old' or somewhere in between?
