Agile (EDIT: The Agile Manifesto specifically) is meant to solve a very specific problem. It's meant to solve the problem of describing software via a contract, taking a long time to build the software described in that contract, and then the software not being useful despite an enormous amount of effort/resources poured into it. Really? The impression I get it's that it's geared towards internal teams who can "iterate" until the cows come home. Contractors work on a fixed time-frame and/or cost, agile doesn't jive well with that unless you're just labour augmentation.
