I'm sitting here in Zurich with some colleagues working on some guidelines for teams who are starting to use Agile in an evironment formely exclusively RUP-based. We have a stack of Agile books, all by big-name authors, from which we are farming references for them to use. Not one of these books has anything (so far as we can find) to say about deployment, actually getting the software into the hands of the user. The very word is not in the index of any of them. Oops.
