Well NYC Mayor Michael Bloomberg agrees with me. It was reported (surprisingly not through his own news network) that he has installed meeting clocks in NYC City Hall to document how much time people waste in them.
According to other companies that have used similar methods before the practices shorten meetings by 20%.
So what do you think are the clocks overkill or worth it. Also take 20% of the meeting out of your schedule how much more could you get done?
