Five working days, five outputs, and a decision on Friday. None of this needs a discovery phase. It needs somebody to sit down with the right people and then write.
Monday is the kickoff, and its output is the out list. Ninety minutes with whoever signs the invoice. What is this engagement for, what does it not touch, and what would make you cancel it. The out list is the part people skip and it is the part that saves the quarter, because an engagement with no boundary drifts toward whatever the loudest department wants.
Tuesday is the systems walk. Not a survey and not a workshop. Sit next to the four or five people whose work is actually going to change, watch them do it, and write down every system they touch and who owns access to it. Two hours per person. You will find shadow tools nobody on the leadership team knows about, which is the point.
Wednesday is the ranked list. Every candidate workflow with a number against it: hours a week, items a month, or dollars. A ranking with no numbers is a preference, and preferences are what you already had before you hired anyone.
Thursday names the first build and writes its acceptance test. One workflow, the system it runs against, and a sentence describing what has to be true for it to count as working. The test gets written before the build, not after, for the same reason an eval gets written before you tune a prompt. Written after, a test is a description of whatever happened to come out.
Friday is the handover. The plan document, the cadence, decision rights, and the measurement baseline captured before anything changes. Then you do one of three things: sign it, send it back with the missing lines named, or stop.
