Lean Software Development is an Agile methodology adapted from lean manufacturing principles, primarily Toyota Production System. It focuses on delivering value to customers by eliminating waste and optimizing efficiency.
At its core, Lean has seven key principles:
1. Eliminate Waste: Identify and remove anything that doesn't add value—unused features, unnecessary documentation, waiting time, task switching, defects, and inefficient processes.
2. Amplify Learning: Software development is a learning process. Encourage feedback loops, testing, and iteration to improve continuously.
3. Decide as Late as Possible: Delay decisions until you have the most information available. This maintains flexibility and allows for better-informed choices.
4. Deliver as Fast as Possible: Rapid delivery provides quicker feedback and reduces the risk of requirements changing during development.
5. Empower the Team: Trust developers to make technical decisions. Self-organizing teams with authority and responsibility perform better than micromanaged ones.
6. Build Integrity In: Develop coherent, usable systems that fulfill user needs. This includes refactoring code regularly and emphasizing quality from the start.
7. See the Whole: Optimize across the entire value stream rather than focusing on individual components.
Lean promotes the concept of "flow"—creating smooth, continuous delivery of value with minimal bottlenecks. It uses visual management tools like Kanban boards to visualize workflow and identify constraints.
Practical techniques include value stream mapping to analyze the current process, small batch sizes to reduce inventory and lead time, and pull systems where work moves forward only when requested by the next stage.
