Finance & Transformation

Business cases, integrations, turnarounds and the programme office that carries them. Run to a number, reported to the board monthly, and closed on a date.

What it is not 

A PMO that reports status and decides nothing.

A business case built to be approved rather than to be true.

A programme that ends when the budget does rather than when the number is reached.

4 steps, in this order, every time.

01

The number

What the programme is worth, in the unit the board reads, agreed before any workstream starts.

02

The sequence

What the customers notice first goes first; the org chart goes last.

03

The office

One plan, one risk register, one monthly report, published inside the firm, not just to the board.

04Ends here

The close

A date, a number, and a programme office your own people are running by month six.

What you are holding at the end.

You leave with 

A business case the CFO signs, not just the sponsor

An integration or recovery plan with dates the board tracks

A programme office that runs without us after month six

9 months two businesses to one operating model

Buy this when 

01A deal has closed and the two businesses are still running two of everything.

02The transformation programme is on its third sponsor and its first delivered benefit.

03Cash is tighter than the forecast said it would be, and the forecast was last month.

If none of these is true yet, the audit is the cheaper place to start.

“Two businesses were on one operating model in nine months. Our previous integration took three years and never really finished.”

The stages run in order, and each is bought on its own: the roadmap from stage 01 prices the rest, so nothing after it is bought blind.

Where it has been bought, and what it came to.
