Code As Documentation vs Manual Architecture Documentation

Developers should adopt Code As Documentation when working on projects where documentation often becomes outdated or when team collaboration requires immediate clarity in the codebase meets developers should use manual architecture documentation when working on complex or long-term projects where clear communication of design intent is critical, such as in enterprise systems, distributed architectures, or legacy codebases. Here's our take.

Code As Documentation

Nice Pick

Developers should adopt Code As Documentation when working on projects where documentation often becomes outdated or when team collaboration requires immediate clarity in the codebase

Pros

• It is particularly useful in agile environments, open-source projects, and teams with high turnover, as it ensures that the code remains accessible and maintainable over time
• Related to: clean-code, code-review

Cons

• Specific tradeoffs depend on your use case

Manual Architecture Documentation

Developers should use Manual Architecture Documentation when working on complex or long-term projects where clear communication of design intent is critical, such as in enterprise systems, distributed architectures, or legacy codebases

Pros

• It helps in onboarding new team members, facilitating code reviews, and ensuring architectural consistency, especially in environments where automated tools may not capture all nuances or decisions
• Related to: architecture-decision-records, diagramming-tools

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Code As Documentation if: You want it is particularly useful in agile environments, open-source projects, and teams with high turnover, as it ensures that the code remains accessible and maintainable over time and can live with specific tradeoffs depend on your use case.

Use Manual Architecture Documentation if: You prioritize it helps in onboarding new team members, facilitating code reviews, and ensuring architectural consistency, especially in environments where automated tools may not capture all nuances or decisions over what Code As Documentation offers.

The Bottom Line

Code As Documentation wins

Developers should adopt Code As Documentation when working on projects where documentation often becomes outdated or when team collaboration requires immediate clarity in the codebase
