Needed the updated version for an MBA, which I received. To be honest- if you are a new grad going straight to an MBA from undergrad it may help you. On the other hand, if you spent 30 plus years in Multi level store leadership - you probably know all of this. I received an A+ in the class and it had nothing what do ever to do with the book. It was ALL prior knowledge. However if you truly have not functioned at that level get the book. It did help me realized what a long term career in corporate Leadership preps you for: getting an MBA to give you academic credit for what you know, the ability to advise working people of how to handle HR issues, Leaves and general operations to keep them and their company safe.
