Fastest PHD, DBA, etc

[Johmford]

Looking purely for least time to complete, any subject,  to just obtain any PhD in any discipline from any institution 

The "least time to complete" PhD is the one you do the most quickly. Because the dissertation is the largest variable, you have no way of calculating this estimate. It varies from person to person, subject to subject, and advisor to advisor. 

The notion that one can do a PhD "in any discipline" is fallacious. Not having a driving purpose, a central goal that keeps you moving forward, is a recipe for disaster in a PhD program. When it gets hard, when it gets messy, expensive, boring, and you're sick of it, doing it in some randomly selected discipline will ensure you quit before finishing.

With PhD (and other doctoral) programs available from universities all over the world, your request is meaningless; there are literally hundreds that meet your definition. Can you be more specific? (You will need to be for yourself, certainly.)

There are “so many” but you’ve failed to mention any. The only meaningless part of this thread is your response as all it happens to be is criticism and no actual value.
