Decision Documentation captures decisions, context, alternatives, and consequences to ensure traceability of technical and organizational strategies. It supports governance and architecture, improves knowledge sharing, reduces duplicated decisions and eases onboarding. Implementation uses simple templates, explicit ownership, and review checkpoints and versi…

Decision documentation records which important choice was made and why.
Architecture Decision Records (ADRs) became popular as a lightweight complement to architecture documentation after teams repeatedly lost the reasoning behind decisions over time.

An ADR connects context, decision, rationale, and consequences. It is a snapshot with a traceable backstory; later records supersede or supplement it instead of erasing the history.
