Architectural decisions are documented using the Architecture Decision Record (ADR) format, which captures problem context, considered options, trade-offs, and final rationale to preserve historical context for engineering teams.

An Architecture Decision Record (ADR) is a structured document that includes the problem statement, existing constraints, considered options with pros and cons, the final decision, accepted trade-offs, and links to related projects.

To write an ADR, document the problem context and constraints, list considered options with their respective pros and cons, state the chosen option, and explain the reasoning and accepted trade-offs behind the decision.

Architecture Decision Records are saved in a designated 06-Resources/ directory, organizing the documents so future engineers can easily reference the historical context and rationale behind past architectural choices.

Yes, the ADR format allows linking to related projects or implementation notes, ensuring comprehensive context is preserved alongside the problem statement, options, and decision rationale.

Use an ADR when architectural decisions are made in meetings and need formal documentation to prevent loss, ensuring future engineers understand the rationale behind choices and accepted technical debt trade-offs.
