Technology architecture - Record
ADR
(Architecture decision record)
An entry recording a decision around how systems, data or integrations were designed
What's it for?
Keeps a lasting record of an important design decision and the reason it was made.
For example…
The architecture team records why a new service will use a managed database rather than the company building and maintaining its own one
Six months later, a developer reads the ADR to understand why the team rejected a cheaper-looking alternative.
