20. 20. Lean If you were to release everyday, how much of your time would be spent on process? - Adrian Cockcroft
21. 21. Lean - Muda 1. Defects (Bad builds) 2. Overproduction of things not demanded by actual customers 3. Inventories awaiting further processing or consumption 4. Unnecessary over-processing (for example, relying on inspections rather than designing the process to eliminate problems) 5. Unnecessary motion of employees (meetings) 6. Unnecessary transport and handling of goods (Approvals) 7. Waiting for an upstream process to deliver, or for a machine to finish processing, or for a supporting function to be completed, or for an interrupted worker to get back to work...
