An Architecture Decision Record (ADR) documents the rationale behind a significant architectural choice. You need an ADR when a decision affects multiple components, cross-cutting concerns like authentication, or deployment strategies, ensuring future audits can trace the context and trade-offs.

You document architectural trade-offs by drafting an ADR with structured sections for Context, Decision, and Options. This format requires explicit justification for why a specific technology was chosen over alternatives, capturing the constraints and narrative for future reference.

The best way to structure an ADR is using a narrative format with Context, Decision, and Options sections. This standardizes scope and constraints, explicitly detailing the justification and trade-offs of cross-cutting architectural decisions to maintain consistency and traceability.

Yes, an ADR template works for deployment strategy and data persistence decisions. It applies to any significant architectural choice by enforcing a structured narrative that captures the context, options, and explicit rationale needed for governance and future audits.

Poor architectural documentation causes audit issues because the original rationale, context, and evaluated alternatives become impossible to understand later. ADRs solve this by standardizing trade-off analysis and requiring explicit justification for every significant architectural decision made.
