Definition of Done (DoD)

• [ ] There is documentation and/or examples for the new functionality (usage/response)

NOTE: Ideally, we should merge only fully implemented and tested features into the master branch. So all the above steps are required for the PR to be merged.
In order to avoid the PRs becoming stale and requiring to be rebased on master, these can be merged after a reasonable time (current agreement is 3 days) if the System Test Engineer Owner's sign-off was not provided (last step in the DoD).

IMPORTANT: Any deviation from the plan should be discussed and agreed as a comment in the Feature file.

Sign-off

• [ ] Product Owner
• [ ] Dev Owner
• [ ] System Test Engineer Owner
