Yes, experienced professionals can pursue PhD programs. If you are a business professional, you can pursue an Executive PhD OR a Part-Time PhD from the most prestigious universities in India. These programs are offered in blended mode. The duration of these programs ranges from 5 years to 8 years. For admission to the Executive PhD and Part-Time PhD, you will need to qualify for the entrance test. These programs are designed for professionals looking to switch their careers in academia and mostly offer academic research.
Being a working professional, you may not get sufficient time to prepare for the entrance test. The blended mode of learning and prolonged duration is another setback for you as a business professional. If you are looking for career growth in the industry, then an Executive PhD or Part-Time PhD may not provide you with the pathway.
Instead of pursuing a Part-time PhD, you can pursue an Online DBA Doctorate from a reputed foreign university. This is a highly flexible doctoral program that is offered completely in online mode. The program offers applied research which is useful for solving real-world problems. You can position yourself for leadership roles in the industry by completing this program in just 36 months.
