A number before the programme, not after it
The baseline, and it is deliberately small.
A few weeks against your actual estate rather than a questionnaire: what you are storing and what it costs to keep, which processes are still run by hand, and where compliance work is being done twice. Each source of leakage gets a figure and the list gets ranked.
That ranking is the point. It means the sequence of the programme is argued from evidence rather than from whoever is loudest in the room, and it means a board is approving an order of work rather than a promise.
It costs a fraction of the programme it corrects, and if the honest answer is that your estate is in better shape than you feared, that is cheaper to learn here than eighteen months in.
