But generally, I’ve found “the source of truth” often hinders more than it helps. And I think the phrase needs to be rethought, if not discarded altogether.
Really enjoyed this take from Ethan Marcotte. It especially resonated with me when thinking about things like “business logic,” and “requirements” which often have substantial effort put toward capture and definition, but are necessarily hard-to-impossible to canonicalize.
