This one is passed on from a friend of mine:
We had some process consultants yammer at us a while back. One of the
ideas that I liked was defining what a "hand off" is.
Roughly, "A hand-off occurs whenever you separate responsibility (what
to do), knowledge (how to do it), action (doing it) and feedback
(learning from doing it)."
The idea is that you lose something (information, motivation etc) with
each hand-off. Not rocket science, but I like the definition -- it's a
handy checklist.
