Follow the normal release process. The toolset being used will determine the release structure. Use System Development Life Cycle (SDLC) Methodology template SDLC S715 as a guideline.
Releases will be more frequent under the iterative process. It is, therefore, important for the release process to be well defined, streamlined, and efficient. Automate as many steps as possible.
It is also important to perform complete (QA) testing of stories as they are completed, including integration testing. The result will be that little testing is required for the actual release.
