What is an architecture decision record?

An architecture decision record (ADR) is a document that captures an important architectural decision made along with its context and consequences.

An architecture decision (AD) is a software design choice that addresses a significant requirement.

An architecture decision log (ADL) is the collection of all ADRs created and maintained for a particular project (or organization).

An architecturally-significant requirement (ASR) is a requirement that has a measurable effect on a software system’s architecture.

All these are within the topic of architecture knowledge management (AKM).

The goal of this document is to provide a fast overview of ADRs, how to create them, and where to look for more information.
