Technical Readiness Review
A concise, evidence-led assessment layout with a decision statement, severity-ranked issue register, delivery analysis and stakeholder questions.
Executive position
Decision first, detail second
The integration boundary must be proven before the programme enters a fixed delivery commitment.
The fictional Aster Identity Platform is ready for a bounded technical proof of concept. It is not yet ready for a production delivery baseline because three external interfaces and the recovery model have not been confirmed.
This is an example of a clear personal assessment. It deliberately separates a judgement from evidence and states which decision is needed.
Scope and evidence
Keep verified facts and assumptions visibly separate
Available evidence
- Solution outline, draft v0.8
- Integration catalogue, revision 03
- Workshop notes from three simulated teams
- Prototype screenshots and an API contract proposal
Outstanding evidence
- Provider test environment and sample payloads
- Credential lifecycle and failure-mode ownership
- Restore test and retention approval
- Named operational acceptance authority
Issue and decision register
Use one owner, one question and one next action per item
| ID | Priority | Finding | Required decision / evidence | Owner |
|---|---|---|---|---|
| R-01 | CRITICAL | Identity token expiryOffline client may hold credentials beyond their accepted lifetime | Approve token validity and degraded-mode rules | Security |
| R-02 | CRITICAL | Revocation propagationNo demonstrated worst-case delivery bound | Define and test revocation consistency | Platform |
| R-03 | HIGH | Unverified vendor interface | Obtain sandbox and contract examples | Integration |
| R-04 | HIGH | Disaster recovery | Perform restore rehearsal with acceptance evidence | Operations |
| R-05 | HIGH | Audit data ownership | Approve retention and visibility matrix | Governance |
| R-06 | HIGH | Release acceptance | Nominate sign-off authority | Sponsor |
Technical implications
Unresolved edges drive delivery risk
Confirm refresh, revocation and device failure behaviour before any client implementation.
Define duplicate handling and event ordering for replayed messages.
Test immutable event recording and traceability from request to outcome.
Illustrative acceptance conditions
- A complete access decision can be reproduced from the event trail.
- Revocation is enforced within an explicitly approved service-level target.
- Interrupted event delivery resumes without silently dropping a decision.
- Recovery is demonstrated from a fresh deployment using documented backup material.
Delivery approach
Use evidence gates rather than an unsupported date
Requirements
All access decisions and failure states are approved.
Technical proof
Integration, replay and recovery tests pass.
Commitment
Only then estimate and approve implementation.
Questions requiring response
Give stakeholders actionable questions
Decisions requested
- Who is the final authority for an access or revocation rule?
- Which source system is authoritative for identity status and revocations?
- What is the maximum acceptable delay between revocation and enforcement?
- Which supplier interfaces have been exercised against a test environment?
- What evidence is needed for operational acceptance?
