01 · The problem
“IT” doesn't own the cutover. A person does.
You've got the spreadsheet — sixty rows, checkboxes, a "who" column half-filled with team names instead of people. The problem was never the rows. Take the phases below; they're yours. Then notice that a slipped line at T-8 is a note, and the same line at T-2 is a crisis.
02 · What you need
“Done” isn't a word she takes on faith.
There are two kinds of line on a move checklist and she treats them differently, honestly. Pick a line and watch what happens to it — including the one where the answer is that she stops and hands it back to you.
03 · How it runs
Every line becomes an owned item.
Set where the asking happens and what a confirmation gets checked against. Every step rewrites itself to match — each checklist line gets a name and a T-minus date, and a slip is surfaced while it's still a note rather than a crisis.
04 · What it's worth
The checklist is genuinely free.
Take the phases above and run the move yourself — plenty of teams do, and a small move only needs one person paying attention. This is for the move where fourteen people each own a line and retyping their answers became your job.
