For decades I have built much of my understanding of reality on dialectical materialism and systems thinking learned from systems thinkers and scientists before me. Maybe the most important of them was Dr. Edwards Deming. He created the “System of Profound Knowledge” (SoPK), which contains basic lessons for people who have worked with Total Quality Management (TQM), Six Sigma, and Lean (Toyota Production Systems). SoPK consists of four ways of "seeing" and understanding the world. Dr. Deming called them "lenses".
