Mark audits business performance metrics and the operating structure sitting underneath those results: the products and services attached to revenue, the brand positioning and route to market, the org design and where decisions are actually taken, the commercial model and its margin, the systems carrying the work, and the compliance exposure behind it.

Bespoke in every instance. The scope is set against the business in front of him rather than a standard checklist, because the cause is rarely in the same place twice.
Most owners can already see the result. This is the week that identifies what is creating it, and it is deliberately brief. You do not require three months of consultants to locate a problem. You require someone who has already operated at the level where it was created.
Concludes with: the diagnosis, the priorities in sequence, and a course of action you can execute immediately.
