Principles of lean Software Development Eliminate WasteThe three biggest wastes in Software Development are:Extra FeaturesWe need a process that allows us to develop just those 20 percent of the features that give 80 percent of the you have requirements churn, you are specifying too early. If you have test and fix cycles, you are testing too BoundariesOrganizational boundaries can increase costs by 25 percent or more. They create buffers that slow down response time and interfere with Quality In If you routinely find defects in your verification process, your process is Code with Test-Driven DevelopmentWrite executable specifications instead of Building Legacy CodeLegacy code is code that lacks automated unit and acceptance Big Bang Is ObsoleteUse continuous integration and nested KnowledgePlanning is useful. Learning is the Scientific MethodTeach teams to establish hypotheses, conduct many rapid experiments, create concise docu-mentation, and implement the best alternative.
Defer Commitment Abolish the idea that it is a good idea to start development with a complete specification. Break Dependencies System architecture should support the addition of any feature at any time.
