Purpose

An Architecture Decision Record captures one significant decision, the options weighed and its consequences, so that the reasoning survives the people who made it. It supports the decision to accept, reject or supersede a design or architecture choice.

Quality Criteria Checklist

Level: Mandatory criteria are the baseline every instance must meet; Optional criteria are advanced and may be deferred.

# Criterion Level ISO/IEC 25010 Characteristic(s) Notes
1 The ID (ADR-NNNN, 4-digit) matches the filename number and is unique and sequential Mandatory Maintainability
2 Context states the problem, the forces (cost, risk, constraints) and the options evaluated Mandatory Functional Suitability, Maintainability
3 At least two options were considered, or the absence of alternatives is justified Mandatory Functional Suitability
4 Decision is stated in one or two unhedged sentences and matches one of the evaluated options Mandatory Functional Suitability, Usability
5 Consequences list both Positive and Negative outcomes Mandatory Maintainability, Reliability
6 Quality-attribute impacts (performance, security, portability, etc.) are named where the decision affects them Optional Performance Efficiency, Security, Portability, Compatibility
7 Affected Artifacts are listed as links, and each is also in CrossReference Mandatory Maintainability
8 Status changes are recorded as new Version History rows with a Change summary and Commit link; retained rows are never rewritten Mandatory Reliability, Maintainability
9 A superseded or deprecated ADR names its successor, and the successor links back Optional Maintainability
10 Written in business or technical language of the domain, with no unexplained abbreviations Optional Usability
11 Status is one of Proposed, Accepted, Rejected, Deprecated or Superseded by ADR-NNNN, and every Version History row uses only these Mandatory Reliability, Maintainability Approved is not an ADR status

Common Defects

  • Decision described only as the chosen technology, with no problem or rationale
  • Only one option listed, presented as if it were a comparison
  • Consequences that list only benefits
  • Decision text hedged ("we might", "probably") or split across several unrelated decisions
  • Status outside the allowed set (for example Approved, Final, Draft)
  • Rewritten history: the status or decision changed in place instead of a new row or a superseding ADR
  • Affected Artifacts missing, so the impact of the decision cannot be traced

Traceability Rule

  • Backward: Business Case checklist (QC-BC-001) for the objectives and constraints that force the decision
  • Forward: Design Class Diagram checklist (QC-DCD-001) and Entity Relationship Diagram checklist (QC-ERD-001) for the design and data structures the decision shapes, and the language code checklists (QC-PY-001, QC-CL-001, QC-CPP-001, QC-CS-001) for the implementation it constrains
