      Not it my experience. Pair programming and testing were harder to
      introduce to an environment foreign to those concepts... and the test
      suites are of course core to the whole methodology.

      I found the XP scheduling methods to be intuitive and make so much sense
      that I would expect anyone to understand and agree. Can you just buy
      whomever doesn't understand lunch, and try explaining it again? Maybe
      putting it in context with the what you describe in the next sentence
      would help?

      So, give them a date. If they don't want the benefits, they don't have to
      have them. Of course, you do need their assistance for continuous
      feedback, so maybe it isn't that simple....
