12. Closure Criteria and Final SDLC Traceability Summary

Project Closure Criteria

The implementation project may be formally closed when all of the following conditions are satisfied:

• The approved production release is operating successfully.
• Mandatory functional and non-functional requirements are accepted or have documented approved exceptions.
• Production smoke tests and post-release verification are complete.
• No unresolved Critical release defect remains.
• Registrar Operations formally accepts the delivered registration workflows.
• Operations staff receive the runbook, monitoring procedures, backup/recovery instructions, and escalation contacts.
• Source code, release artifacts, database migrations, design documents, test evidence, and approvals are stored in approved repositories.
• Outstanding enhancements are transferred to the maintenance backlog or a separately approved project.
• Final project risks and lessons learned are documented.
• The Project Sponsor approves closure.

Example End-to-End Trace

Business need: prevent invalid enrollment when two sections overlap.

1. Requirement: FR-06 Conflict Validation.
2. Acceptance Criterion: AC-02.
3. Design: Registration Rules Service plus schedule-conflict UI feedback.
4. Implementation: server-side meeting-overlap validation.
5. Test: TC-06 Schedule Conflict.
6. Release evidence: passed test result in Test Completion Report.
7. Operational control: validation failures recorded through application monitoring and applicable audit logging.

Final Deliverable Set

The completed documentation package gives the project team a reviewable chain from business case through production maintenance. Every major requirement, design decision, implementation component, test, release control, and operational responsibility has an identifiable owner or artifact.

Final Approval

The Project Sponsor signs the Project Closure Record after receiving confirmation from Registrar Operations, University IT, QA, and Operations that production acceptance and handover criteria have been satisfied.
