The distance online MBA is a part-time MBA format, and one that is largely undertaken by students who wish to remain in their current role while they study. Employer-funded candidates will make up a certain proportion of each class. However, the majority of students will be self-funded candidates who have taken the initiative to pursue an MBA, but who cannot afford to forego their salary or to relocate or simply do not wish to.
Yet, this is where the real appeal of an MBA online becomes apparent. While traditionally, a part-time MBA candidate would be limited to schools in their local area, they can now choose to study at any one of a solid selection of highly-respected international business schools, enjoying the benefits of the schools network, access to world-class faculty and of course the ability to put a prestigious, globally-recognized school on their rsum.
Technological advances have, of course, allowed for great progress and innovation in delivery. As recently as 15 years ago, schools would still have had to largely send out physical copies of textbooks and contact would have been relatively slow paced. Today, the paradigm is very different. Video content, podcasts, e-books, instantaneous 24 hour contact, social media and apps all second nature to the digital native mean that the experience today is a very different proposition, with a combination of freely available and bespoke platforms utilized. Indeed, much of the technology that once would have been associated solely with online provision is now also used in full-time MBA provision.
Partially as a consequence of the huge leaps made in provision (other factors are also at play see career benefits), the distance online MBA has grown hugely in popularity. QS applicant research shows that as many as 18.3% of applicants consider online MBA study, and 8.7% distance learning (respondents are, however, not limited to choosing just one format, so there is overlap here). This represents a huge increase on the 4.4% who were open to studying by distance in 2008.
The distance online MBA, it seems, is due to play a key role in the future of both the full-time and the part-time MBA, as a more and more diverse applicant pool seeks high-quality MBA provision.

Fulltime MBA is better because it has more opportunities to learn basics of management from learned faculty and interaction with diverse background students. Pedagogy followed in full time is different from conventional teaching. It includes case studies, role playing, workshops, simulation exercises, presentation, lectures, video show, guest lectures, etc. You will miss this any part time or distance learning program. Business world moves on the basis of networking. There are no opportunities to network in part time or distance learning program. Above all, generally, universities do not allow part time and distance learning program students to participate in campus placement.
