I would like to say that I think it is good that we have disagreements on the DEN. I think it is a strength of the DEN, not a weakness. However, I think we sometimes get to personal with no real purpose. One example of this, for me, is: “Well, I guess we knew different Demings. Mine was a teacher named Dr. W. Edwards Deming.” I doubt this statement is meant to be taken literally, and if it is not I do not see what it adds to the discussion. I point this out not because I think this is some bad act that should be punished but that I think we need to continue to develop a sense of how we wish to express our disagreements and I think that we should try to do so more constructively.
For the past 60 years we’ve been looking for the magic bullet that will improve the quality of our products, services and lives. In the 1940s, we applied statistics through sampling, SPC and design of experiments to improve our products. In the 1950s, we used quality cost and total quality control to bring about quality improvement. In the 1960s, zero defects and MIL-Q-9858A drove the quality improvement process. In the 1970s, quality circles, process qualification and supplier qualification became key quality issues. In the 1980s, employee training in problem solving, team activities and just-in-time inventory were the things to do.”
I find this statement so far from the truth that it would seriously damage any PDSA with this as an accepted assessment of history. I do not believe Deming had such an inaccurate view (of course I may be wrong). I do believe we need to improve our practice of Quality (and to do that we need to understand what happened in the past and why it was not more successful). The idea that Design of Experiments (DoE) was at the core of some Quality Movement to me is not at all accurate.
