Deployment, release approval, rollback, and production verification

Deployment activity

Deployment promotes an approved release candidate into the intended environment. Early sprint increments may be deployed only to staging, while Sprint 4 produces the planned production version 1.0.

Release readiness checklist

• Release scope approved.
• Required acceptance criteria pass.
• No open Severity 1 or Severity 2 defects.
• Database migrations tested.
• Production backup completed before migration.
• Production secrets and environment configuration verified.
• HTTPS verified.
• Error monitoring enabled.
• Rollback procedure reviewed.
• Release notes prepared.

Deployment procedure

1. Create the approved release version and source-control tag.
2. Verify the latest valid production backup.
3. Enable maintenance protection when required.
4. Deploy the tested application build.
5. Apply approved database migrations.
6. Run production smoke tests.
7. Review application errors, response times, and database connectivity.
8. Disable maintenance protection.
9. Record deployment result, version, approvers, and timestamp.

Production smoke tests

• Login succeeds for a valid test account.
• Dashboard loads correctly.
• A transaction can be created and retrieved.
• Budget information displays correctly.
• Authorization blocks another user's record.
• Logout invalidates the authenticated session.

Rollback triggers

• Authentication unavailable for normal users.
• Unauthorized financial-data access detected.
• Materially incorrect financial calculations introduced by the release.
• Database migration failure.
• Sustained severe application failures after deployment.

Rollback procedure

1. Stop exposure to the faulty release when necessary.
2. Restore the previous known-good application version.
3. Reverse migrations only when a tested rollback exists.
4. Restore a database backup if required by the incident assessment.
5. Run production smoke tests.
6. Record and investigate the failed release as an incident.

Release approval gate

G-03: Production release requires QA release recommendation and Product Owner approval. The Project Sponsor provides final business authorization for version 1.0.
