I like to call it small "a" agile vs. big "A" Agile. The difference being big "A" Agile has companies selling prescriptive solutions, ticketing systems, books, consultants, etc. and then management that hears about a silver bullet and thinks it solves all their woes. Small "a" agile is an iterative process with a tight feedback loop, small testable deliverables and a backlog where prioritized items bubble up resulting in other items getting stale. Stale items are good in the sense that you didn't build, test and deliver something that is of little to no value.
