SOPs are usually written for audit theatre or onboarding decks. The people doing the work carry the real rules in their heads — and in workarounds the SOP forbids.
Duvo starts from evidence: walkthroughs, interviews, documents, and system hops. When those sources conflict, we reconcile them into a reviewed record instead of picking the cleanest slide.
That record is what makes improvement, training, migration, and automation honest. Without it you automate fiction.
