Architecture decision records prevent lost or duplicated decisions by providing a standardized template. ADRs ensure team alignment by documenting decision makers, context, rationale, consequences, and alternatives for significant software design choices.

To write an ADR document, use a standardized template to capture the title, date, status, and decision makers. Include sections for context, the decision itself, rationale, consequences, alternatives considered, implementation action items, and references for complete traceability.

Architecture decision records should include required metadata like title, date, status, and decision makers. Add sections for context, decision rationale, alternatives, consequences, implementation actions, and references to link related ADRs and maintain stakeholder alignment over time.

Yes, this ADR format works for system migrations by documenting driving constraints, options considered, and expected positive or negative consequences. It creates an immutable record that guides future implementation work and maintains operational consistency across the team.

Architecture decision records should not be used for trivial implementation details that lack significant tradeoffs. Reserve ADRs for significant software design choices where documenting context, constraints, alternatives, and rationale provides durable value for future teams.
