How to Write Architecture Decision Records That Engineers Actually Use

Architecture Decision Records (ADRs) often fail not because teams skip writing them, but because they contain the wrong information, according to a guide published on DEV Community. An effective ADR should focus on one core purpose: documenting a hard-to-reverse decision and the reasoning behind it, ideally within 600 words or roughly one page. Key content should include the real constraints that created conflict, the alternatives seriously considered and why they were rejected, and the trade-offs accepted — including the unwelcome ones. The guide warns against writing ADRs for unresolved decisions or creating them retroactively just to satisfy a process checklist, as both practices erode trust in the records. Once a team's ADRs gain a reputation for being performative rather than genuine, engineers stop reading them altogether.
