DBA and Ph.D. are both doctoral level degrees. Both require the completion of a major piece of research and a written thesis, but they differ in terms of their emphasis, career paths, and contribution to original knowledge.
A DBA makes an original contribution to
practitioner knowledge, to investigating and solving
real-world problems. The DBA thesis will involve critical evaluation of literature from a management practitioner perspective. This results in publications in practitioner, application-oriented journals. A DBA is for candidates who want to advance their careers as
thought leaders and
change agents in their professions or industries and to
develop practical research skills in order to investigate, and propose solutions to, complex management problems. Although they may also teach at academic institutions, this is typically not one of their primary roles.
A Ph.D. makes an original contribution to
academic knowledge or to
theory. The Ph.D. thesis is founded on a critical evaluation of academic literature. This results in publications in academic journals, targeted to those in academia. A Ph.D. is best suited to those who wish
primarily to pursue a full-time career in academic institutions.
Ph.D. and DBA Research Differences: An Example
Business Model Generation is a global best-selling book by the creators of the Business Model Canvas. The
Business Model Canvas is a one-page visualization tool for building, evaluating, and testing business models, suitable for large corporations, small to medium enterprises, or start-ups.
Let’s compare DBA vs Ph.D. projects on the topic of business models
A DBA project would, in contrast, start with a tangible problem or real-world scenario. This could be the uncertainty faced by an established company when new competitors adopt new business models, or it could be the intended application of a business model from one industry to another.
The DBA project would start with a clear specification of the nature and scope of the real-world problem or scenario. Literature on business models would be examined to identify empirical studies on the application of the business model concept in practice, with a special emphasis on finding examples of successes and failures. The project would probably develop or modify a business model, and then test its feasibility or likelihood of success.
The overall aim of the DBA project would be to make an original contribution to knowledge through improved industry or business best practice on business models.
A Ph.D. project would probably start by looking at the academic literature on business models to identify current issues being debated and discussed by researchers.
This would involve an examination of the literature which preceded the development of the business model canvas as well as more recent literature, including criticisms of the business model and business model canvas concepts.
The theory underpinning the business model concept would be examined, as well as cases of its successes and failures, and potential limitations. This analysis of past research would reveal unanswered questions, tentative hypotheses, or gaps in existing literature that could be explored through further investigation.
The overall aim of the Ph.D. project would be to make an original contribution to knowledge through an improved or enhanced understanding of the theory (and potentially also practice) of business models.
