In January and February, I outlined six common management myths. The point of those two posts was to help education systems leaders see what not to do. I’m now turning to a set of principles that can be used by these same leaders to guide their transformation work. Last month, I introduced the 14 Principles for Educational Systems Transformation. In this post I’ll describe the third principle, Cease Dependence on Inspection to Achieve Quality. It is worth noting that the 14 Principles are mutually supporting, so it is important to understand all of them rather than studying them in isolation. An in-depth discussion of the Principles for Transformation can be found in Chapter 3 of my recently released book Win-Win: W. Edwards Deming, the System of Profound Knowledge, and the Science of Improving Schools.
