It's all a question of balance

The Master of Business Administration (MBA) differs from other management degrees by providing a broad perspective on knowledge, skills and competencies rather than a narrow focus on specialist areas. This is doubtless one of the principal reasons why its appeal among public servants has grown so significantly in recent years.
At the same time, however, the MBA has faced criticism for having limited relevance to actual management practice. Even an article published by Harvard Business School, which is widely credited with having invented the qualification, has questioned whether there is nowadays too firm a fixation on scientific research and warned that business schools risk "institutionalising their own irrelevance".
