A Doctorate in Business Administration (DBA) can be beneficial to those who are seeking advanced managerial positions, teaching jobs or opportunities for consulting. It provides deep knowledge in the theory of business, strategy, and management techniques, establishing you as a subject specialist in your field. But the commitment of time, expense and effort is substantial. For those who are in the middle of their careers and beyond, having a DBA will improve your chances of advancing in the field; however, the value of your investment will depend on your personal goals and your industry. In the end, it's worth it when you're interested in research, education, training, or strategic business planning at the highest level.
