You Paid for the Project. Where Is the Proof It Was Tested?
When a vendor delivers a data warehouse, migration, or integration project, one question should come before final payment: where is the proof it was tested? Not verbal reassurance, not assumptions, but documented evidence showing which checks were run, against which data, and with what results. Because without that proof, you are not signing off a reliable delivery — you are accepting hidden risk that may only surface months later in reporting, AI outputs, or regulatory submissions.
