Lean principles

While going thru a book on Lean Principles by Mary & Tom Poppendieck, I want to preserve quick notes, which form the essence of the lean approach to software development.

1. Eliminate waste - Whatever gets in the way of rapidly satisfying a customer need is waste
2. Amplify Learning - Encourage learning and discovery instead of first time perfect approach.
3. Decide as late as possible - In an evolving market, keeping design options open is more valuable than committing early.
4. Deliver as fast as possible - Design, implement, feedback, improve. The shorter these cycles are, the more can be learned.
5. Empower the team - Involving developers in the details of technical decisions is fundamental to achieving excellence.
6. Build integrity in - integrity comes from wise leadership, relevant expertise, effective communication, and healthy discipline; processes, procedures, and measurements are not adequate substitutes.
7. See the whole - When individuals or organizations are measured on their specialized contribution rather than overall performance, suboptimization is likely to result.
