A successful AI workflow demo does not reveal the cost of its first change. Test a likely change request before choosing how to buy. An extra approval branch can affect permissions, pending requests, handover, regression tests, and commercial responsibilities beyond the visible screen change. Choose one concrete change and trace who gains authority, who maintains it, and what should happen to work already in progress. Ask for regression and rollback evidence, including operator handover. Check what remains configuration and what becomes a separately maintained customization. Agree on change ownership and fees before committing. A realistic change exercise makes build, buy, and configure options easier to compare fairly. Original article explainer.
