Review, merge lanes and delivery

Understand how parallel changes reach an integration branch and then a release.

Start with the delivery record

Open Delivery → PRs to inspect proposed changes and their checks. Previews & Deploys shows the available deployment evidence. A merged change and a successfully deployed change are separate states.

What is a merge lane?

A merge lane is an integration branch for a group of related work, such as an epic. It lets related changes be reconciled before they reach the shared integration/release path. It is different from a column on the task board.

Availability and prerequisites

Merge-lane routing and merge-train execution are separately controlled capabilities. The reviewed implementation defaults these controls off; ask your organization administrator which are enabled. Do not assume a visible route or a guide means automatic merging is active.

Review before promotion

  1. Confirm the intended repository, base branch and lane.
  2. Review the diff, acceptance evidence and required checks.
  3. Resolve conflicts and review holds; do not bypass them merely to move the card forward.
  4. Approve or request changes according to your role and organization policy.
  5. Verify the integration/release result and deployment health before treating the work as delivered.

When parallel work collides

Check overlapping files and dependencies. A lane reduces coordination work but does not guarantee conflict-free changes. Keep rollback and ownership decisions explicit.
