Acceptance is a handoff decision
Deployment acceptance asks whether a particular system can be used for an agreed purpose under defined conditions. It is different from a purchase, an installation, or a successful first connection. The acceptance owner needs enough evidence to decide what may proceed and what remains restricted.
Identify the person authorized to make that decision before the appliance is placed. The installer may confirm technical steps, while the customer owns permission and operating risk. Keep those roles explicit even if the same person participates in several parts of the review.
Assemble evidence around the actual appliance
Start with an exact platform baseline and the intended placement. Then connect the relevant test results to that baseline. Hardware-family claims and generic architecture material can provide context, but they do not replace evidence for the system being accepted.
The acceptance packet should distinguish completed review from requested evidence. If a document is missing, say so. A blank status is easy to mistake for an administrative omission; an explicit Not reviewed status makes the unresolved decision visible.
Include the operating dependencies
Custody, connectivity approval, release authority, recovery, and maintenance are part of the deployment. A technically functioning appliance may still lack an accepted operating owner or an agreed recovery path. Those gaps belong in the same decision record as software or hardware findings.
For RookHaven, the documented public gates include governed signing custody, exact-platform validation, applicable external resilience controls and audit witnesses, recovery exercises, and independent review. This checklist does not assert that those gates have passed for any specific candidate.
Record conditions that require reassessment
Acceptance should state the purpose and baseline covered, any restrictions, unresolved exceptions, and the changes that trigger review. Avoid a generic “approved” label that can later be detached from the conditions behind it.
Use the worksheet below to prepare the packet. Add evidence references, observed results, reviewer names, and dates. An exception needs a rationale and an authorized owner; it should not silently disappear when the document is summarized for procurement.
Your working record
Adapt these criteria to the engagement. The CSV includes blank evidence, status, owner, and review-date fields. Nothing is pre-marked as passed. Scroll the table horizontally on small screens.
| Gate | Required record | Acceptance check |
|---|---|---|
| Authorized use | Purpose, targets, placement, and customer permission. | The intended use is explicitly approved. |
| Exact platform | Hardware, firmware, configuration, OS, and test references. | Evidence matches the deployed baseline. |
| Custody and release authority | Physical custody and signing/approval responsibilities. | Material changes have a governed authorization path. |
| Connectivity and workspace | Approved boundaries, dependencies, and activity scope. | No unapproved access assumption is needed to operate. |
| Applicable resilience controls | External dependency, fencing, and witness review where relevant. | Required dependencies have evidence or a documented blocking gap. |
| Recovery | Exercised scenario, results, deviations, and return-to-service authority. | Recovery criteria are met or the limitation is explicitly unresolved. |
| Independent review | Scope, findings, remediation, and exceptions. | The acceptance owner can distinguish reviewed claims from unreviewed ones. |
| Handoff | Operations owner, maintenance process, retirement plan, and reassessment triggers. | Someone owns the deployment after the evaluation ends. |
Worked example: installed does not mean accepted
Illustrative scenario: an appliance is installed and reachable. The exact platform record is complete, but the recovery exercise has not occurred. The installation record can be closed while deployment acceptance remains pending.
The acceptance owner records the missing recovery evidence and any permitted evaluation-only activity. The team does not rewrite the pending gate as a pass simply because equipment is already on site. That distinction protects both the customer’s decision and the technical team’s account of what was actually validated.
