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. To either run a firm or a business or any set up for that matter, there needs to be a management set up in place which deals with the clients, customers, stakeholders and partners. For example, if an Engineer runs a code, it doesn't get business. The Managements of 2 organisations need to discuss the needs and benefits of a certain outcome. Management course helps you run business effectively.
