Roles

Remember one person can have more than one role. In conventional companies each role is given to different persons in different business units. In devops each team lives all those roles and thus takes responsibility over the whole development cycle.

Additionally in some cases the release build and deployment is automated to automatically bring changes into test and even production systems.
