Architecture Decision Records (ADRs) capture the context, rationale, and consequences behind significant architectural choices. They provide traceable decision history, facilitate onboarding for new engineers, and ensure governance of design trade-offs across teams.

To create an Architecture Decision Record, duplicate the standard ADR template and add it to the docs/adr directory. Populate the record by detailing the context, the specific decision made, and the resulting consequences.

The best way to standardize architectural decisions is to implement structured ADR templates and lifecycle guidance. This ensures consistent documentation of context, decisions, and trade-offs, making design choices easy to audit and review.

You should document architecture trade-offs using an ADR when evaluating significant architecture options. This preserves the historical reasoning behind design choices, enabling consistent governance, audits, and knowledge transfer across engineering teams.

Yes, this ADR approach requires specific repository conventions, primarily storing decision records within a docs/adr directory. Following these conventions ensures consistent documentation, easy auditing, and straightforward access for new team members.

ADRs are limited to capturing historical context and decisions; they do not automatically enforce architectural compliance. Teams must manually maintain the records and adhere to the lifecycle guidance to ensure the documentation remains accurate and useful.
