Starting with easy but important applications. are run to ensure high-quality code. Code is compiled if necessary and then packaged by a build server every time a change is committed to a source control repository, then tested by a number of different techniques (possibly including manual testing) before it can be marked as releasable. With more frequent releases, the number of code changes in each release decreases. Having the expert on the team helps to build the motivation and momentum to move to CD from inside the team. By using the deployment pipeline pattern. How do you do that? A pillar of modern application development, continuous delivery expands upon continuous integration by deploying all code changes to a testing environment and/or a production environment after the build stage. When selecting the first few applications to migrate to CD, choose the ones that are easy to migrate but that are important to the business. With continuous delivery, every code change is built, tested, and then pushed to a non-production testing or staging environment.  These ASRs require a high priority and cannot be traded off lightly. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production. Give a team a visual CD pipeline skeleton that has the full CD pipeline view but with empty stages for those they cannot implement yet.
