Architecture Decision Records (ADRs)
Why Document Decisions?
- •Knowledge transfer helps new team members understand why decisions were made
- •Avoid re-litigation by preventing the same discussions from repeating
- •Track evolution so you can see how the architecture has changed over time
- •Accountability comes from recording who made decisions and when
ADR Best Practices
- •Keep them immutable. Do not edit old ADRs. Create a new ADR that supersedes the old one
- •Store with code by keeping ADRs in your repository, for example in /docs/decisions/
- •Link related ADRs by referencing earlier decisions that influenced this one
- •Be concise by focusing on the why rather than the what
ADR Template Structure
A good ADR includes a short title, context for what prompted the decision, the decision itself, the options you considered, and your rationale. If the decision changes the system in a meaningful way, add consequences so readers know what to expect.
