This task can be delegated in turn to different members of the group. A tape recording could be used and transcribed later. Members may be required to put down their own notes which are then collated later On other items summary notes could be put down. Such reports could be read back at the beginning of the next meeting. Where there is a task formally assigned by me then the type of out put required will also be specified.
Output is important because it gives a sense of achievement.
Output is also important because it can show up a session that might have seemed interesting at the time but was really very general waffle. The trouble is that output is tedious and takes up time. Whenever this seems to be the case then output must be sacrificed for 'liveliness'. The organiser can hand the output task to individuals by asking them to list the points which seemed important to them.
