Lean software development also provides significant insight into the importance of increasing the cadence of releases. A fundamental principle of lean is to reduce work in process (WIP), and a key way to do that is to have smaller production releases and deploy more often. Reducing WIP increases quality, which in turn leads to reduced cost, both of which enable you to release faster. It is a virtuous improvement cycle. Reduced WIP also leads to a reduced need for managing the work and for any replanning due to changed stakeholders needs, resulting in less overhead and cost.
