I think the rankings show employment data. Ashridge has a weak alumni network in comparison to the universities: they are much larger.

In terms of integration, programmes like Ashridge with cross-functional core courses and fewer electives will tend to be more integrated. I would expect Cranfield to be good at that, maybe Henley too. Warwick, Oxbridge and London will be less integrated and more functional.

I went through quite a bit in this site. My final question pertains to Alumni Network & integrative themes(four nos) of Ashridge, may be employability factor too, as compared to rest, also Oxford, Cambridge, LBS, Warwick, Henley.
Thanks

Ralph, I think the tricky thing is that this person has started from looking at distance learning courses: the EMBAs at LBS and Oxbridge are around double those DL prices, and Ashridge is somewhere in between. Ashridge's post-MBA salary growth is pretty similar to other UK EMBAs (Ashridge, Cranfield, Henley and Oxford are all around 60%) and Ashridge post-EMBA salary is similar to Cass, Cranfield, Henley, Imperial and Warwick (All around $145K). But Ashridge does have the integration this person is looking for, and admissions are more flexible there.

Oxford and London Business School are well worth applying, but they are perhaps more of a stretch for this applicant.

I have admissions which are mix of both EMBA(Ashridge, Birmingham & Durham), Manchester & then Aston DL(applied part-time, offered DL with some scholarship). Did not try the really top ones, since they have application fees & very high tuition fees(less scholarships), also well spread out schedule I need for travel. Some of the big ones need you to be there every 2 weeks or 3 weeks for a few days.
Thanks
