Lessons Learned Using arc42 in a Real DevOps Team

Introduction

This tutorial provides insights and lessons learned from implementing the arc42 architecture template in a real DevOps team. It highlights the importance of structured documentation, effective tooling, and the integration of architecture practices within an agile environment. Whether you’re a team member or a leader in product development, these steps will guide you in utilizing the arc42 framework effectively.

Step 1: Transition to the arc42 Template

• Assess existing documentation to identify unstructured content that needs to be organized.
• Convert the unstructured documentation into the arc42 format, which includes:
  • Context and scope
  • Building blocks
  • Runtime view
  • Deployment view
  • Cross-cutting concepts
  • Architectural decisions
• Store the completed documentation in a centralized wiki for easy access and collaboration.

Step 2: Implement Docs-as-Code

• Recognize the significant role tooling plays in documentation quality.
• Transition to a Docs-as-Code approach, which allows documentation to be treated like code, promoting version control and collaboration.
• Use tools such as:
  • Markdown or AsciiDoc for documentation formatting
  • Git for version control
  • CI/CD pipelines to automate documentation updates

Step 3: Address Key Decision Points

• Identify important architecture decision points relevant to your DevOps team, such as:
  • Handling developer prose: Ensure clarity and technical accuracy in documentation.
  • Managing outdated documentation: Regularly review and update to maintain relevance.
  • Documenting architecture decisions: Clearly record decisions and their rationale for future reference.

Step 4: Integrate with Kanban Methodology

• Use the arc42 template to align documentation efforts with your team's Kanban process.
• Create a microsite based on AsciiDoc that can be easily updated and referenced during sprint planning and reviews.
• Ensure that documentation updates are part of your workflow, preventing bottlenecks in communication.

Step 5: Quality Assurance of Documentation

• Establish a quality assurance process for documentation to avoid common pitfalls:
  • Involve multiple team members in reviewing documentation for accuracy and completeness.
  • Separate business-oriented content from technical content to prevent confusion.
• Implement regular check-ins to ensure documentation stays current and useful.

Conclusion

By following these steps, you can effectively leverage the arc42 architecture template within your DevOps team. Emphasizing structured documentation, utilizing appropriate tooling, and integrating practices with agile methodologies will enhance your workflow and improve communication. As you move forward, continually assess and adapt your documentation practices to meet the evolving needs of your team and projects.
