Guys, thanks for your responses.
I agree that the DBA seems more a "practical" doctorate rather than purely academic. It is also regarded as a professional qualification - which I think is a USP in itself?
As for my rationale for considering the DBA: I have been working as a management consultant for 2.5 years now and already have a Masters - achieved distinction for dissertation. So what I would like your opinion on is: do you guys think doing a DBA would "train me" to be a better consultant, i.e. will I become better at critical analysis, being more objective, and being able to come up with more pragmatic recommendations for my clients. As for my career aspirations: I hope to be an independent consultant in around 10-12 yrs time - currently work for big consulting (IT) firm. I also would consider lecturing once a week at a business school. To do this, I would need to be an "Industry Figure" and I think the DBA may help achieve this credibility. The bad news is that I know some DBAs who aren't exactly minting money...but I think they just haven't positioned themselves properly. Do you guys know anyone who has actually completed the DBA?
As for business school: have also heard good things about Henley, but I don't want to spend that big (£8000/yr) as opposed to Durham (£5000/yr) or Strath/Aston (£2000/yr), unless it really makes a significant difference where you do it. I just wish more universities offered the course!!
Please let me know what you guys think...
