    Lean Development

    Lean development is the application of Lean principles to software development. Lean got its start in manufacturing, as a way to optimize the production line to minimize waste and maximize value to the customer. These two goals are also relevant to software development, which also follows a repeatable process, requires particular quality standards, and relies on the collaboration of a group of specialized workers in order to get done. 7 Lean Development Principles The seven principles of Lean development are: Eliminate Waste Build Quality In Create Knowledge Defer Commitment Deliver Fast Respect People Optimize the Whole.
