When I was sitting in the council chair, I knew asset data mattered. What I didn't have was a clear path from good intention to working reality. That's what this guide is: a twelve-stage roadmap for implementing ADAC in a council, across four phases. It begins where it really counts, with governance and the standard itself, before any software enters the picture, then works through your local rules, the pipeline, and going live. The map I wish I'd had.
