Using a Process Behavior Chart to Prove that Improvement Has Occurred

How do you trend infrequently occurring data?

The best way that we have found (and the technique we teach in the 2-Day TapRooT® Trending to Manage Performance Course) is the Process Behavior Chart (example shown above).

What does the example above show? That the time between incidents with a particular root cause has increased significantly and stabilized at a new, more infrequent level. It changed from an average of 15 days between incidents with this root cause to an average of 60 days between incidents.
