I think someone posted recently that David, at one of the new seminars, mentioned that during the weekly review you'd go through the approrpriate support material for each project. If you were a PM, for example, you might go through the project plan for that project, a teacher, the weekly lesson plan. This would be your source of ideas for Next Actions.
This tells me, however, that you don't need to keep every next action for the project, particularly delegated ones, in your list. For example, If I'm managing project X and there are 10 next actions delegated to other team members in the plan, I don't need to have all 10 in my "Delegated" list AND in the project plan also.
Am I getting this right?
