Most schools use HBS cases for their classes. The only difference that I can think of is that the case will be presented more succintly in the magazine with less data as opposed to the cases which will be handed out in class.
Hope this helps.
That's my hope. Thanks for your thoughts.
I also wonder how the HBR Case Study relates to a normal b-school case study. I've never seen a MBA case study so I wondered if they are similar or not even close.
