Transform white collar departments into "professional service firms" whose sole, powerful asset is knowledge.Idea: You are boss of a 23-person finance department in a division of a big company.  Or, rather, you were boss of the finance department.  Now, per our suggestion-model, you are Managing Partner, Finance Inc., a full-fledged professional service firm which is a wholly owned subsidiary of your division.Goal: Learn from the best professional service firms!  Transform your unit!  Today, even after re-engineering done well, the "department" doesn't look much like McKinsey, Andersen or Chiat Day.  (And that's an understatement!)Aim, in short: Cool people (call them "talent") working on cool projects with cool clients.  The aim redux: A cool Finance/Purchasing, IS, HR, Sales department. Why not?The cool professional service firm is just that: cool people/talent, a portfolio of cool projects, cool clients.  Period.  It's only asset -- literally -- is brains. It's only product is projects. It's only aim is truly memorable client service.So step #1, then, is the organization (PSF) . . . transforming "departments" in which white collar folks work into way cool professional sercie firms adding way cool value by doing way cool "stuff".
