How Do You Trend Performance Data?
How do you trend your performance data?
Can you tell the difference between normal random variation and a real, significant trend?
Can you prove that a trend is significant (good or bad)?
Do you know the special techniques needed to trend infrequently occurring data (like accidents, incident, sentinel events, quality problems, equipment failures, and almost all root cause analysis data)?
Do you know when to use Pareto Charts to spot areas begging for improvement and when NOT to use Pareto Charts?
I gave a presentation (Trending, Root Cause, & Performance Improvement) at the last VPPPA Conference about the problems with trending and some advanced trending methods. A pdf of the presentation is attached below. Click on it and see if you are interested in learning more. If you are, please sign up for the next Advanced Trending Course in Gatlinburg, Tennessee, on April 3-4, 2006. For more course information, click here.
