Design Architect - Quality Standards

Overview

This document defines comprehensive quality standards for the Design Architect persona in the BMAD Method. These standards ensure consistent, accessible, and scalable design system implementations that meet business objectives and user needs.

Quality Framework

Quality Dimensions

The Design Architect quality assessment framework evaluates deliverables across six key dimensions:

  1. Design System Consistency (25%)
  2. Accessibility Compliance (20%)
  3. User Experience Quality (20%)
  4. Technical Implementation (15%)
  5. Documentation Quality (10%)
  6. Brand Alignment (10%)

Quality Scoring

Each dimension is evaluated on a 5-point scale:

  • 5 - Exceptional: Exceeds all standards and best practices
  • 4 - Excellent: Meets all standards with minor enhancements
  • 3 - Good: Meets minimum standards with some improvements needed
  • 2 - Fair: Below standards, requires significant improvement
  • 1 - Poor: Does not meet standards, requires complete rework

Overall Quality Score = Σ(Dimension Score × Weight)

Quality Thresholds

  • Release Ready: ≥ 4.0 overall score
  • Review Required: 3.0 - 3.9 overall score
  • Significant Rework: 2.0 - 2.9 overall score
