Deming's System of Profound Knowledge

Four ways of looking at a problem that work together: seeing it as a system, understanding variation, asking how we know what we know, and paying attention to people.

How to use it. When a problem looks simple, you have probably ignored at least one of the four. Variation explains most operational pain. The "how do we know" lens explains most learning failures.

How it gets misused. Cherry-picking a single method, such as Plan-Do-Study-Act, without the rest. The four lenses depend on each other. Variation without the people lens becomes process tyranny. The people lens without variation becomes vibes.
