"Scrum/Agile (when properly used) has two main purposes... to better predict delivery of a particular technical capability (ie: when can I ship feature "foo" to customer "xyz"), and focus on keeping the product under development in a shippable state throughout the development process (ie: even though feature "foo" isn't done, I can still ship A, B, and C with minimal incremental work)."

A lot of people think that those are the core purposes of agile.... and that's part of the problem.

The real core purpose of agile is shortening the feedback loop. If you aren't shortening the feedback loop you are wasting your time.
