      If you switch pairs often, and start each pairing session with a quick
      review of what has been done by the lone programmer, risk already is
      reduced quite a lot, in my experience.

      For junior people, my last team found that what worked best was to
      pair in the morning, and to work alone in the evening. That way, they
      could review for themselves what they learned in the morning, and try
      some low risk steps for themselves. YMMV.

      Cheers, Ilja
