Nw Sa Critique Dimensions

Architecture Quality Critique Dimensions

Dimension 1: Architectural Bias Detection

Technology Preference Bias

Pattern: tech chosen by preference, not requirements. Detection: ADR lacks comparison matrix, choice not mapped to requirements, justified only as "best practice." Severity: HIGH.

Resume-Driven Development

Pattern: complex/trendy tech without requirement justification. Examples: microservices for 3-person team, Kafka for 100 req/day, service mesh without complexity. Detection: complexity exceeds team size/requirements, tech adds resume value not solves problem. Severity: CRITICAL.

Latest Technology Bias

Pattern: unproven tech (<6 months, small community) for production. Detection: check maturity, community, LTS, fallback plan. Severity: HIGH.

Dimension 2: ADR Quality Validation

Missing Context

ADR lacks business problem, technical constraints, or quality attribute requirements. Future maintainers cannot validate. Severity: HIGH.

Missing Alternatives Analysis

No alternatives (min 2 required). Each must be evaluated against requirements with rejection rationale. Severity: HIGH.

Missing Consequences

Omits positive/negative consequences and trade-offs. Quality attribute impact not analyzed. Severity: MEDIUM.

Dimension 3: Completeness Validation

Missing Quality Attributes

Architecture doesn't address required attributes. Verify: performance (latency, throughput) | scalability | security (auth, data protection) | maintainability (modularity, testability) | reliability (fault tolerance, recovery) | observability (logging, monitoring, alerting). Severity: CRITICAL.

Missing Performance Architecture

Performance requirements exist but no optimization strategy (caching, indexing, rate limiting, CDN). Severity: CRITICAL.

Dimension 4: Implementation Feasibility

Team Capability Mismatch

Requires expertise team lacks. Verify learning curve reasonable, training plan exists. Severity: HIGH.

Budget Constraints

Infrastructure costs exceed budget. Verify cost estimate exists and aligns. Severity: HIGH.

Testability Validation

Architecture prevents effective testing. Components must enable isolated testing with ports/adapters. Severity: CRITICAL.

Dimension 5: Priority Validation

Validate roadmap addresses largest bottleneck.

Q1: Largest bottleneck? (timing data must confirm primary problem) Q2: Simpler alternatives considered? (rejected alternatives required) Q3: Constraint prioritization correct? (quantified by impact, constraint-free first) Q4: Data-justified? (key decision with quantitative data)

Failure: Q1=NO (wrong problem) | Q2=MISSING (no alternatives) | Q3=INVERTED (>50% solution for <30% problem) | Q4=NO_DATA for performance
