🔧 Documentation Standards​

Required Elements​

All conceptual documentation must include:

Executive Summary​

  • Business Goal: What business outcome does this concept achieve?
  • Target Audience: Who needs to understand this concept?
  • Key Takeaways: 2-3 bullet points summarizing the main insights
  • Business Impact: How does this affect day-to-day operations?

Visual Diagrams (Mandatory)​

  • Sequence Diagrams: For time-based interactions between components
  • Flowcharts: For business process flows and decision points
  • Architecture Diagrams: For system structure and relationships
  • State Diagrams: For entity lifecycle and transitions

Implementation Context​

  • Technical Decisions: Why were specific approaches chosen?
  • Alternatives Considered: What other options were evaluated?
  • Trade-offs: What are the benefits and limitations?

Process Workflows​

Creating New Conceptual Documentation​

1. Identify the Need​

  • Complex feature requiring architectural explanation
  • Business process spanning multiple aggregates/services
  • Integration pattern used in multiple contexts
  • Frequently asked questions from stakeholders
  • Cross-module workflow requiring coordination

2. Planning Phase​

  • Define target audience and their knowledge level
  • Identify key concepts that need explanation
  • Plan required diagrams and visual aids
  • Gather input from domain experts and stakeholders
  • Determine success metrics for comprehension

3. Documentation Phase​

  • Start with executive summary and overview
  • Create visual diagrams first (they often reveal missing details)
  • Write detailed explanations referencing the diagrams
  • Include concrete examples and scenarios
  • Add implementation context and design decisions

4. Review Process​

  • Technical Review: Architects and senior developers verify accuracy
  • Business Review: Business analysts confirm business logic alignment
  • Clarity Review: Test with target audience for comprehension
  • Visual Review: Ensure diagrams are clear and properly formatted

5. Publication & Maintenance​

  • Add to this index with appropriate status
  • Link from related domain and API documentation
  • Update when underlying systems change
  • Gather feedback and iterate as needed

Visual Design Guidelines​

Diagram Complexity Management​

  • Single Focus: Each diagram explains one primary concept
  • Progressive Detail: Start simple, add complexity in subsequent diagrams
  • Consistent Notation: Use same symbols/colors across all diagrams
  • Clear Labels: All components and flows clearly labeled

Text-to-Visual Balance​

  • Visual First: Start explanations with diagrams, then elaborate with text
  • Reference Integration: Text should reference specific diagram elements
  • Standalone Diagrams: Each diagram should be understandable independently
  • Caption Context: Provide context in diagram captions

Accessibility Considerations​

  • Color Independence: Don't rely solely on color to convey meaning
  • Text Alternatives: Provide text descriptions of visual elements
  • High Contrast: Ensure diagrams are readable in various display conditions
  • Scale Flexibility: Diagrams should be readable at different zoom levels
