Write BIG, large enough to read from the back of the room.
Prepare the charts in advance for agenda, ground rules, key ideas in a presentation, decisions and assignments made, and issues to be discussed later. Pencil in notes to yourself on the chart for things you want to cover before the meeting begins.
To stimulate creativity, use diagrams, pictures and sketches.
Use color. Take notes in one color, ideas in another, and highlight or organize the information with a third color.
Post charts on walls for information that the team has agreed upon.
Turn pages over and hide data when there is not agreement. The old pages can be a block to further discussion and synthesis. Get new data and incorporate the old ideas worth keeping on a fresh page.
When in doubt, write it. If it is not important or useful it will become obvious to the whole team later. Deciding not to write it, usually alienates the contributor.
Keep separate sheets for unrelated items to be dealt with later. Be sure to write them up so that they are not forgotten and so that they do not become a distraction.
Be very careful of editing or reinterpreting what someone else says in a way that they do not agree with when you are writing it up on the charts. Listen when they speak and then check back with them to make sure you are recording accurately.
Don't give up the power of the pen. The meeting leader should do the writing. If other people need to make use of a chart to express an idea, encourage them to do so, but do not let them run the meeting.
