I am looking for case studies that talks about the BSC in professional services firms.  I have found some articles on law firm application, but I am thinking more of a consulting flavor than a law firm. 

As we all know, there is a lot of information out there on BSC in corporations and public sector non profit etc.  This is all translatable., but it would help me communicate with my audience if I had some PSF examples to point to.

Any ideas?
