The technic of discussing a point or going through MOs:
First talk it over untill we have silence, or coll-down. We then will ask the first initiater to summarize the subject, and with the help of the others, make it agreeable.
Some times one subject is related to another subject. So we can move between subjects. We have to write them down and summarize each agreeable point.
The facilitator is the wise person who see it all, with the help of the group. But more simple work can be done by the managers.
It is very important to simulate the talk on a board. Preferably, white-board. The Symboles will be with mind maps but with clear sentences.
