      Just as a personal experience report I've found that short bursts of
      pairing (max three hours) has worked well when I've introduced people
      to pairing for the first time.

      I started trying it as an experiment in the if-it-is-hard-do-it-more-
      often tradition before I'd come across Arlo's experiment - and it
      seemed to work well.

      Yes - it highlighted problems (like "only Adrian knows how this bit
      works" :-) - but having had them highlighted we could address them
      explicitly. Which was nice.

      In addition to the stuff Arlo talked about, my own theory is that the
      shorter periods had the additional advantage that it was harder to
      fall back into the "old way" of doing it. It's harder to sit back and
      watch somebody code if you know that you're going to be in front of
      the code with somebody else later on that day.

      When I'd previously tried introducing pairing with one-pair-per-story
      I found it much harder because:
      1) They were also in the process of figuring out how to write short
      stories. So stories were long - and the information didn't spread
      2) It was easier to fall back into having one "expert" per story, with
      the other person just kibitzing[1] occasionally rather than actively

      Because of this they didn't see much advantage to pairing - so didn't
      want to continue. Short regular pair changes seemed to fix that.



      [1] I can't believe I managed to spell "kibitzing" correctly first
      time - woot!

      Hi Chris: I, for one, am more for trying it and seeing what results I get. Analyzing someone else s data is considerably less interesting to me. It is possible

        Hi Chris:

        I, for one, am more for trying it and seeing what results I get.
        Analyzing someone else's data is considerably less interesting to me.
        It is possible that mine is more representative of the views here, but
        I'm not sure that's true. In any case, I'm fairly sure you're not
        alone, you're just the most vocal representative of that view.

        On the other hand, if you can't get access to Arlo's data in a way
        that would make it possible for you to reliably verify it, you could
        always design your own experiment to prove the part of the problem
        that is interesting to you.
