The terms Continuous Integration (CI) and Continuous Delivery (CD) are both widely used in software engineering: CI as the adoption of agile principles; CD as a combination of agile methodology techniques and a high-quality delivery process. Whereas CI addresses building a software product from the contributions of single members of a development team in a controlled though lean way, the goal of CD is validation of every change, preferably in an automated way, so that it is potentially shippable.
