Dear Aarush, even an Engineer needs a Manager to guide him in a certain project. An senior Engineer may have the required technical skills but management skills need to be learnt. That is how the need of MBA has emerged. Apart from a course detour from Engineering to Management, there are not many disadvantages to quote and refer to. Infact it is a way to move up the ladder for promotions and opportunities. Even if there is a bunch of experienced Engineers, you still need a Manager or a Management structure to smoothly run the technical department. This is where studying MBA fits.
