Stakeholder Persona: External Architect Evaluator

Field Value
Category EXTERNAL Stakeholder
Actor Type human
Primary Goal Assess whether Spec Kitty architecture and decision model are robust enough for long-term organizational adoption.
Persona ID aud-ext-architect-evaluator
Created / Updated 2026-03-01
Domain / Context Spec Kitty architecture 2.x
Status canonical

Overview

  • Role Focus: System boundaries, decision traceability, and architecture lifecycle sustainability.
  • Primary Function: Evaluates whether Spec Kitty supports defensible architecture governance and evolution in real organizations.
  • Environment / Context: Teams with multi-year codebase stewardship and high sensitivity to architecture drift.

Core Motivations

  • Professional Drivers: Preserve coherent architecture direction and avoid undocumented, ad-hoc decision drift.
  • Emotional or Cognitive Drivers: Prefers explicit rationale and model consistency over implicit convention.
  • Systemic Positioning: Gatekeeper for architecture standards and governance fitness.

Desiderata

Category Expectation / Need Description
Information Strong architecture narrative Needs consistent domain, context, container, and component descriptions with clear boundaries.
Interaction Traceable decision flow Expects architectural behavior to be linked to ADR rationale and supersession history.
Support Comparative evaluation material Wants enough detail to compare Spec Kitty against existing architecture governance approaches.
Governance Explicit authority boundaries Requires clear separation between host authority and external integration adapters.
Decision Authority Adoption sign-off influence Can endorse or block architecture-level adoption decisions.

Frustrations and Constraints

  • Pain Points: Documentation that is aspirational but not anchored to tested behavior.
  • Trade-Off Awareness: Accepts initial complexity if it prevents long-term governance entropy.
  • Environmental Constraints: Legacy architecture commitments, audit requirements, and migration risk exposure.

Behavioral Cues

Situation Typical Behavior Interpretation
Stable / Routine Reviews structural coherence periodically Maintains long-term architecture health through regular review.
Change / Uncertainty Requests explicit alternatives and consequences Protects against narrow, under-explained architectural choices.
Under Pressure Enforces minimum architecture invariants Prioritizes boundary integrity over short-term convenience.

Collaboration Preferences

  • Decision Style: Trade-off analysis with explicit consequences.
  • Communication Style: Structured, rationale-heavy, and citation-backed.
  • Feedback Expectations: Clear mismatch analysis between architecture docs and runtime/test behavior.

Design Impact

  • Affected By: C4 layering quality, lifecycle FSM clarity, and runtime boundary modeling.
  • Needs From Design: Architecture corpus that remains trustworthy during evolution.
  • Risk If Ignored: Rejection due to low confidence in governance durability.
  • Acceptance Signal: Architecture docs remain coherent under change and align with test-inferred behavior.

Measures of Success

Dimension Indicator Type
Performance Time to evaluate a major architecture proposal Quantitative
Quality Ratio of decisions with explicit alternatives and traceability Quantitative
Growth Confidence in maintaining architecture coherence over releases Qualitative

Narrative Summary

The External Architect Evaluator focuses on whether Spec Kitty can sustain architectural integrity over time, not just bootstrap a project quickly. They need clear boundaries, traceable decisions, and consistent behavior modeling before recommending adoption.
