A single source of truth is agreed in every boardroom and implemented in almost none, because the hard part is not the platform but deciding which system wins an argument. This guide gives you the working: what the term means once you have to build it, how to choose the first domain, the four architecture patterns and what each really costs, the matching and survivorship rules that settle disputes, the integration layer that keeps the record current, a costed ninety-day plan, the four measures that prove it worked, and the mistakes that quietly undo the whole thing in year two.
