Therefore, you are the one in control of the event. Timing Be polite but firm about timing. Keep the program running to schedule. Don't let speakers get into pointless arguments with members of the audience. Intervene to allow others' questions or comments to be put forward or move the discussion towards other points of interest.
Charts Keep charts and graphs simple, with the printing large enough to be read easily.
When preparing charts, it is best to stand at the distance you estimate the audience will be from the speaker, and make sure you can read the print yourself. When speaking about a chart, use a pointer to avoid obscuring the chart with your body. One way of making a large field day more personal and allowing more discussion is to break the crowd into small groups. Each group starts at a different speaker or display, and moves among the demonstrations. There is minimum need for public address systems because groups are small.
