Support and changes

Update the working environment safely after handover.

Result

Every post-handover change has a reason, owner, bounded scope, test, decision, and rollback path. The accepted scenario remains reproducible or the client deliberately adopts a new verified baseline.

Change record

Record the request, affected component, old and new versions, owner, reason, expected effect, permissions change, control example, acceptance criteria, result, rollback action, and final decision.

Actions

1. Identify the current accepted package and preserve a recoverable copy or immutable version reference.
2. State the observed problem or required outcome; do not update solely because a newer version exists.
3. Review release notes, ownership, compatibility, permission, data, and licence changes before installation.
4. Change one component or one coupled release set at a time and record the exact new version.
5. Run a de-identified control example plus the acceptance criteria most likely to regress.
6. Compare output, evidence, permissions, and recovery behaviour with the previous accepted baseline.
7. Accept the change and update the handover manifest, or restore the previous version and verify the original scenario again.

Check

The change record names the author, date, reason, affected baseline, versions, permission difference, test evidence, decision, and rollback result. The package points to one unambiguous accepted configuration, and a fresh session can still complete the core route.

If it fails

Stop further updates and restore the last accepted version through the recorded recovery path. Verify the original scenario after rollback. Before retrying, classify the failure as installation, authentication, authorisation, compatibility, instruction, execution, or output quality.
