You document software architecture decisions by creating Architecture Decision Records that capture context, options considered, and consequences. This structured approach preserves rationale and ensures decisions survive personnel changes to support future refactoring.

An Architecture Decision Record is a structured document that captures significant architectural decisions and their trade-offs. You need one during design sessions, technology choices, and onboarding to preserve rationale and facilitate future work across projects.

The best way to structure decision records for onboarding is using a repeatable ADR template that enforces context, decision, rationale, and consequences. This aids new team members in understanding why certain technology choices were made.

Yes, you can use ADR templates for technology choices across multiple projects. The templates provide consistent documentation standards and guidelines, ensuring that architectural decisions and their design trade-offs are uniformly captured regardless of the project scope.

Teams lose rationale behind software architecture decisions due to personnel changes and lack of authoritative documentation. Creating Architecture Decision Records solves this by preserving context and consequences, ensuring knowledge longevity and governance.
