You've just delivered the project. The client wants more. Are you going to charge for it? Or the quote is due tomorrow and the number on the page is last year's number, nudged. Days like that are when principals decide the practice needs looking at properly. The Strategy Day exists so that the look happens now, not in the quarter after next.
Principal-led practices where the work is good and the margin does not reflect it. Principals carrying the numbers alone. Practices that need answers this month, not this year.
Practices before their first projects, or anyone looking for motivation rather than structure. The tools on the Start here page cost less and fit better.
