DATA SANITY: A Quantum Leap to Unprecedented Results

What they’re saying about Davis…

"Thank you Davis…Absolutely spot on well done and good for you to continue to show the courage to tell it like it is."

"Was at your excellent presentation last week and I am a convert! I returned home and have already converted my falls data into something much more meaningful. Was able to plot where 3 changes occurred with resulting results. Found common cause variation all over the place and I am now ready for the next Board Meeting."

"Thank you so much for the interesting lecture yesterday. You are an excellent speaker and have an amazing ability to captivate your audience totally throwing away (at least in my mind) the reputation of statistics as being excruciatingly boring. I thoroughly enjoyed your lecture."

In the real world of quality improvement, we must look for repeatability […]

The Wisdom of David Kerridge, Part 1

I discovered a wonderful unpublished paper by David and Sarah Kerridge several years ago. Its influence on my thinking has been nothing short of profound. As statistical methods get more and more embedded in everyday organizational quality improvements, I feel that now is the time to get us “back to basics”—but a set of basics that is woefully misunderstood, if taught at all. Professor Kerridge is an academic at the University of Aberdeen in Scotland, and I consider him one of the leading Deming thinkers in the world today.

What is the cost of dis-Harmony in one’s organization?

It is believed that the fate of many companies could be altered for the better if workers were more motivated. So, when things go wrong, why is the knee-jerk reaction to blame the workers for their poor attitudes and lack of work ethic?
