Documentation is not bureaucracy when it removes repeated questions, preserves context, and keeps decisions from getting lost in chat history.
- Documentation
- Decision Records
- Communication
- Architecture
- Teams
1. Write the context, not just the conclusion
A decision without context is hard to reuse. Capture the problem, the constraints, and the alternatives so future readers understand why the team chose a particular path.
That record saves time when the same trade-off comes back later.
2. Keep the format short enough to read
Useful documentation should be easy to scan. A short decision record, design note, or issue summary is often better than a long polished document that nobody opens.
Clarity beats ceremony.
- State the problem clearly.
- List the options you rejected.
- Record the reason the chosen path wins.
3. Attach documentation to the work itself
Documentation works best when it lives near the decision it supports. Put it in the repository, the issue, or the design note that people will actually find.
If the context is too far away from the code, it will be forgotten.
4. Review it when reality changes
Good documentation is not permanent. Revisit the note after shipping, after incidents, and after major architectural shifts so it reflects what the team now knows.
That keeps the record trustworthy instead of historical only.
Practical example: lightweight decision note template
A small template keeps documentation practical and keeps decisions easy to revisit.
Example: Decision note
# Decision: API idempotency keys for payment retries
## Problem
Duplicate charges can occur when clients retry on timeouts.
## Recommended approach
Require Idempotency-Key on payment create endpoints.
## Tradeoffs
- Adds key storage and cleanup logic.
- Prevents duplicate side effects under retries.
## Final note
Re-evaluate in 90 days based on retry patterns.
