## Artifact Under Review

- Instance reviewed: [BC-001] (docs/business-case.md)
- Checklist used: [QC-BC-001] (`QC-BC-001`)
- Independence: S01 is the only stakeholder and is also the recorded author, so the reviewer-is-not-author rule cannot be met. The documents were drafted by Claude on S01's behalf; S01 reviews and signs. This is a known limit of a one-person project, not a clean independent review.

## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | ROI/Cost-Benefit analysis is quantitative, or where qualitative, is explicitly justified | Pass | Cost-Benefit table is explicitly qualitative and says why (no money involved). |
| 2 | Risks are identified with documented impact and mitigation | Pass | Three risks, each with impact and mitigation. |
| 3 | Success criteria are measurable, stating explicit targets rather than vague aspirations | Pass | Five criteria with targets and a measure each. |
| 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | `### In Scope` and `### Out of Scope` are separate. |
| 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs rather than re-described inline | Pass | Stakeholders table cites S01 to S03 only; no roles are re-described. |
| 6 | Methodology and quality-standard foundation are stated explicitly (e.g. ISO/IEC 25010, Larman) | Pass | Methodology section names the framework, ISO/IEC 25010:2023 and the coding conventions. |
| 7 | Assumptions and constraints are explicit and clearly distinguished from one another | Pass | Fixed in v2: the first draft had no duration, although MIL-001 to MIL-003 and PP-001 cite one. Constraints now state 2026-10-05 to 2026-10-12. |
| 8 | Document supports executive decision-making with a clear, unambiguous recommendation | Pass | Recommendation is a single "Proceed" with a reason. |

## Overall Verdict

Go — all mandatory criteria pass. Criterion 7 first failed (missing duration constraint) and was fixed in the same change as BC-001 v2.

## Action Items

| Action | Owner | Due |
| --- | --- | --- |
| Add the duration constraint to BC-001 (done in v2) | S01 | 2026-10-06 |
