Creating lifecycles
A lifecycle is a template for the stages of work in a release. To define a lifecycle, specify the phases in the lifecycle and the gates for each phase.
Lifecycles contain ordered lists of phases, and each phase represents the stages of work on the release. You can customize the phases in a lifecycle to match how your releases move from the beginning to the end of the release pipeline. In this way, the lifecycle is a template for the work in a release. When you create a release, you must select a lifecycle for it before you can assign release environments to the lifecycle phases.
Each lifecycle phase can have a gate. A gate is a quality status that must be met before a deployment can be started in the phase. You define quality statuses to include in the gates. See Creating and assigning quality statuses.

If the default lifecycle does not accommodate your release process, you can modify it or create one.
