DesignChurn isn't waste. It's the sound of figuring things out.
The unavoidable, generative friction of making something. Unlike manufacturing, design can't be optimized into a repeatable process: the changing requirements aren't inefficiency, they're discovery. A project that doesn't churn is a project that hasn't learned anything yet.
The unavoidable iteration cycle in creative and product work where changing requirements are a form of discovery, not inefficiency.
