If agile was the opening act, continuous delivery is the headliner.

Kurt Bittner, Forrester


Continuous Delivery (CD) is a set of practices and principles in software engineering aimed at, building, testing, and releasing software, faster and more frequently. These principles help reduce the cost, time and risk of deliveringchanges, and ultimately value, to customers by allowing for more incremental changes to applications in production.Wikipedia, 2017
