OK, I have to tell you, in case you are wondering, that Michael Porter and his theories are indeed ubiquitous. His theories are taught world wide. If you are in business school-or pursuing and MBA-you need to know what he’s about. Really. Whether you agree with him or not. Almost every lecture I’ve had here at CBS has referenced his work in one way or another. Not that I ever doubted my fine Bostonian professors, but I’m here to tell you from the trenches, that it’s true. It’s important to know his work. Read him, know him, love him. Then there is the beloved Kathleen Eisenhardt. Another need to know. Trust me.
