In my line of work, I estimate that I am in meetings at least 2-3 times day. This results in my participation in about 750 meetings a year. Meetings that match their surroundings lead to a feeling of being connected and fulfilled. A meeting space should be able to change its look, feel and functionality at a moment's notice. Lighting, furniture, and meeting tools should be able to change to accommodate the users of the space.
Meetings are theatre.
Business is entertainment. Meeting room designers should take their cue from stage designers who understand the essence of creating an image to match the desired need. All within the same physical space, but two different environments. Technology can improve a meeting when the correct mix of tools and message are utilized. Technology tools like PowerPoint will not make you a better speaker, but they can make a good speaker worse.
