The Improvement cluster

How systems get better over time.

Why these together

Each entry is a different scale of the same loop. Deming is the philosophy. The Three Ways is the operating model. Improvement Kata is the daily practice. Build-Measure-Learn is the product-level cycle. ToC tells you where to apply the loop. Feedback Loops is the principle underneath all of them.

Framework 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.
Framework Improvement Kata A four-step pattern for getting better at anything. Understand the direction. Grasp the current condition. Set the next target condition. Run experiments toward it.
Framework The Three Ways A way of seeing DevOps as a whole. Optimise flow from idea to production. Amplify feedback from production back to development. Build a culture of continuous experimentation and learning.
Pattern Build-Measure-Learn Build the smallest thing that tests your idea. Measure what happens. Learn what to do next.
Principle Feedback Loops Every system improves at the rate of its slowest feedback loop. Shorten the loops between action and outcome.
Framework Theory of Constraints The speed of any system is set by its slowest part. Improving anything else makes no difference.
Framework Lean Enterprise An operating model for large organisations that want to be fast. Optimise the whole value stream. Build feedback into every step. Treat the business as a portfolio of experiments.
