MBA - not enough to be a good manager!

For someone who has spent a long time in the field of management (first as a student and now as a top level manager) to say that management education lacks this is something. There seems to be a growing sense of dissatisfaction and incompleteness about the experiences gained as management students.

More and more people seem to be writing about the things lacking in B schools worldwide. Or maybe its just me who's reading too much into a few articles written by certain disgruntled people!
