Formal Documentation vs Informal Documentation

Developers should learn and use formal documentation to improve code maintainability, facilitate onboarding of new team members, and ensure compliance with industry standards or regulatory requirements meets developers should use informal documentation to facilitate team collaboration, onboard new members, and document ad-hoc decisions or code rationale that don't fit into formal specs. Here's our take.

Formal Documentation

Nice Pick

Developers should learn and use formal documentation to improve code maintainability, facilitate onboarding of new team members, and ensure compliance with industry standards or regulatory requirements

Pros

• It is particularly critical in large-scale projects, open-source software, and enterprise environments where clear communication and reproducibility are paramount, such as in API development, system architecture, and safety-critical applications
• Related to: api-design, version-control

Cons

• Specific tradeoffs depend on your use case

Informal Documentation

Developers should use informal documentation to facilitate team collaboration, onboard new members, and document ad-hoc decisions or code rationale that don't fit into formal specs

Pros

• It's particularly valuable in agile environments, open-source projects, or when rapid iteration makes formal documentation impractical, as it reduces knowledge silos and improves code maintainability
• Related to: documentation-writing, code-comments

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Formal Documentation if: You want it is particularly critical in large-scale projects, open-source software, and enterprise environments where clear communication and reproducibility are paramount, such as in api development, system architecture, and safety-critical applications and can live with specific tradeoffs depend on your use case.

Use Informal Documentation if: You prioritize it's particularly valuable in agile environments, open-source projects, or when rapid iteration makes formal documentation impractical, as it reduces knowledge silos and improves code maintainability over what Formal Documentation offers.

The Bottom Line

Formal Documentation wins

Developers should learn and use formal documentation to improve code maintainability, facilitate onboarding of new team members, and ensure compliance with industry standards or regulatory requirements
