Use cases & scenarios

Compromises

  • Inconsistent diagrams without central guidelines.
  • Outdated diagrams if changes are not maintained.
  • Wrong level of detail may foster discussion instead of decisions.
  • Use standardized templates for recurring diagram types.
  • Keep diagrams focused; link details instead of showing everything.
  • Version diagrams alongside related code or docs.

I/O & resources

  • Requirements or goal description
  • Existing architecture or process documents
  • Access to team and cloud storage
  • Diagrams in PNG, SVG, XML
  • Embeddable diagrams for Confluence/Docs
  • Templates and libraries of reusable shapes

Description

draw.io (diagrams.net) is a browser-based diagram editor for creating architecture, process, and flow diagrams. It provides collaborative editing, templates and cloud storage integrations. The tool supports exporting to common formats and embedding diagrams into documentation, making it useful for technical communication and design alignment.

  • Fast visualization of complex relationships for teams.
  • Embedding and export for documentation and presentation.
  • Supports collaborative work and alignment processes.

  • Not specialized for model-driven architecture descriptions.
  • Performance limits can occur with very large diagrams.
  • Standardization requires disciplined templates and naming.

  • Number of diagrams created

    Measures diagrams created per time period to evaluate usage.

  • Average diagram size

    Indicates complexity and potential performance impact.

  • Share of versioned diagrams

    Shows how many diagrams are managed in a versioning process.

⚠️ Technical debt & bottlenecks

  • Outdated diagrams without owners.
  • Inconsistent templates across projects.
  • Missing automation for diagram updates from architecture changes.
Scalability for large diagramsConsistency across autonomous teamsAutomatability of diagram updates
  • A single huge diagram for the entire system instead of modular views.
  • Using diagrams as a substitute for specifications instead of a complement.
  • Private storage of diagrams that are relevant to the team.
  • Ignoring naming conventions leads to unclear artifacts.
  • Forgetting export and access rights before sharing.
  • Too many detail layers in one view make the diagram unusable.
Basic understanding of diagram notations (e.g. UML, C4)Ability to structure technical relationships visuallyVersioning and documentation practices
Clarity of communication between stakeholdersTraceable and versioned documentationSeamless integration into existing toolchains
  • Need for notation guidelines
  • Access and storage locations (cloud vs. self-host)
  • Compatibility with existing documentation formats
