Deciding on who does what in an institutional change process may take one or a few hours in a plenary meeting, but is more often communicated over through emails and telephone calls over a period of a few weeks.
As probably indicated in the matrix, one or more actors will steer the whole process and check whether everybody does his or her part satisfactorily. If not agreed beforehand, the activities need to be planned in time.
