THE SHORT ANSWER
Ask who would notice within a day if the system stopped, and ask the person who runs the process rather than the leader who filled in the form. Marco Di Santo's October 27, 2026 check puts four questions to every answer claiming a system in production (which system, which process, how long, who would notice in a day), with three months as his reference for how long. The time question is the one that misleads: in my per-seat sunset, 12 accounts sat as on plan for eighteen months, paying committed minimums and using less than the minimum, and nobody would have noticed if it stopped until we lost two of them. An expense agent I put in an approver's seat ran two weeks, approvals rose 40%, about $2,400 was wrongly approved, and finance found out by switching it off. Verify the fourth question with two numbers from the FDE scorecard, the date of the last change the customer made without you and whether the workflow was switched off or routed around by day 60, and then run the gate as an action: pick a date and switch it off for a week.
