The seven principles, put to work
Lean Software Development rests on seven principles. This library is organized around them — each document below is a principle (or a core tool) as one team actually practices it, not as a poster on a wall.
One team, all ten documents
Every document in this library comes from the same fictional-but-fully-worked workplace, so the numbers line up across the set: the value stream map explains the metrics dashboard, the A3 explains the quality checklist, and the decision logs explain the release plan.
