Thanks for your thoughtful reply!
I have yet to see groups sustain the level of focus and energy they demonstrate in workshops during their normal 9-to-5 routines. There are too many interruptions and too much task-switching in the day-to-day for people to concentrate in the same way they can during workshops.
The trick is not letting the workshop become a one-off. That’s the main point of this post: The workshop must meet the broader needs of the group so that the joint time spent together is not an isolated incident, but a communal focusing of attention in service to the broader context the group is operating in.
