# RC-001 Review of BC-001 Business Case ## Metadata | Key | Value | | --- | --- | | ID | RC-001 | | CrossReference | [BC-001], [QC-BC-001], [QC-LANG-001] | ## Version History | Date | Status | Author | Reviewer | Change | Commit | | --- | --- | --- | --- | --- | --- | | 2026-11-06 | Proposed | Jens Tirsvad Nielsen | AI as stand-in for S01 | Initial version | [a07d05b] | --- ## Artifact Under Review - Instance reviewed: [BC-001] - Checklist used: [QC-BC-001] and [QC-LANG-001] (the type is written in the PO language) - Scope: full review. Round 1 found the defects named under Overall Verdict; they were fixed in the document and the criteria re-checked in round 2, which this record shows. - Language and domain: en / it - Language reviewer: S01 (a person; confirmed criteria 3, 5 and 9 of QC-LANG-001 in chat on 2026-11-06) - Mode: autonomous, not independent (the reviewer is `AI as stand-in for S01`; S01 is also the author, the Product Owner and the named reviewer) ## Checklist Results | # | Criterion | Status | Evidence/Notes | | --- | --- | --- | --- | | 1 | ROI/Cost-Benefit analysis is quantitative, or where qualitative, is explicitly justified | Pass | Section "Cost–Benefit Assessment" is qualitative and says why: "this is a personal learning project with no revenue, so numbers would add no information" | | 2 | Risks are identified with documented impact and mitigation | Pass | Five risks, each row has Impact and Mitigation (flaky timing tests, token leak, wrong repository, translations, screenshot capture) | | 3 | Success criteria are measurable, stating explicit targets rather than vague aspirations | Pass | Six criteria with Target and Measure (e.g. 100 % tests green via `python -m pytest`, 0 runtime dependencies, at least 5 topics). The measure of criterion 2 ("captured in the lecture-step screenshots") is checked by MIL-002 Go criterion 2 | | 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | Subsections "In Scope" and "Out of Scope" | | 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs rather than re-described inline | Pass | The "Stakeholders" table keys on S01, S02, S03 and gives only the interest in this project; roles and power are not re-described. [SA-001] is in CrossReference | | 6 | Methodology and quality-standard foundation are stated explicitly (e.g. ISO/IEC 25010, Larman) | Pass | "Methodological and Standards Foundation" names the framework, the ISO/IEC 25010:2023 tags and the coding-conventions skill | | 7 | Assumptions and constraints are explicit and clearly distinguished from one another | Pass | Separate sections. Round 1 defect (fixed): the constraint read "greater than 3.13 (3.13 or newer)" (ambiguous) and "No runtime dependencies unless needed" contradicted success criterion 3 (0 runtime dependencies). Now "Python 3.13 or newer" and "No runtime dependencies" | | 8 | Document supports executive decision-making with a clear, unambiguous recommendation | Pass | "Recommendation": "Proceed", with the reason | ## Language and Domain Results | # | Criterion | Status | Evidence/Notes | | --- | --- | --- | --- | | 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder | Pass | Metadata has `Language` = `en` and `Domain` = `it` | | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list | Pass | `en` is a BCP 47 code; `it` is in the domain table of `docs/artifact-registry.md` | | 3 | The content (prose and table cells) is written in the stated language | Pass | Confirmed by S01 (a person) in chat, 2026-11-06. The English wording is correct | | 4 | The register matches the one the registry gives for the artifact type | Pass | IT Executive English: short, outcome-oriented prose; technical detail (file names, commands) is limited to Scope and the Success Criteria measures, where it makes them checkable | | 5 | Domain terms are the PO terms of the domain's dictionary, with no synonyms | Pass | Confirmed by S01 (a person) in chat, 2026-11-06. No DICT exists; the PO confirmed the terms are correct | | 6 | Metadata keys, section headings, IDs and statuses are in English | Pass | All keys, headings and statuses are the framework's English ones | | 7 | No translated twin (`..md`) exists beside the document | Pass | The `docs/` listing has no twin file | | 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again | N-A | No earlier accepted version exists and the language has been `en` since the first row | | 9 | A reviewer competent in the domain, and in the language, has confirmed that the domain terms are used correctly | Pass | Confirmed by S01 (a person) in chat, 2026-11-06. S01 reads English and knows software and IT; the IT domain terms are used correctly | | 10 | Abbreviations are spelled out on first use, in the stated language | Pass | Round 1: GUI, PyPI, API and CI were used unexpanded; expanded on first use in round 2. README and ISO/IEC are names, not abbreviations to expand | ## Overall Verdict Go. No Fail on QC-BC-001 in round 2. Round 1 found two defects (criterion 7: ambiguous Python version wording and a contradiction between the dependency constraint and success criterion 3; QC-LANG-001 criterion 10: unexpanded abbreviations), fixed in the document. Criteria 3, 5 and 9 of QC-LANG-001 were Pending and are now Pass: S01 (a person) confirmed the English wording and the IT domain terms in chat on 2026-11-06. All Mandatory rows pass, so the verdict is Go and the Version History row of the document is Accepted. The review remains `Mode: autonomous, not independent` for the rest. Finding: no Domain Dictionary exists, so criterion 5 has no reference; it is not in the plan and is not added here. ## Action Items | Action | Owner | Due | | --- | --- | --- | | Confirm criteria 3, 5 and 9 of QC-LANG-001 as a person (Closed: confirmed by S01 in chat, 2026-11-06; criteria set to Pass, verdict Go, document row Accepted) | S01 | 2026-11-06 | --- [BC-001]: ../../business-case.md [QC-BC-001]: ../../../framework/qc/artifacts/qc-business-case.md [QC-LANG-001]: ../../../framework/qc/artifacts/qc-language-domain.md [a07d05b]: https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/054-speed-calc-decorator/commit/a07d05b385e6b831b90731aefe08f078ebb951ca
