An old wag has it that meetings are where minutes are recorded and hours wasted. The effectiveness of administration (and management) in both public and private sectors is to a large extent dependent on the clarity and focus of the frequent meetings at different levels. Most often, meetings meander along for a long time, and ends with considerable opportunity cost bill.
In this context, the Nudges blog points to a clock that tells you how much your office meeting is costing (number of people in the meeting x average hourly wage). All you need is to simply enter the number of people in the room, ballpark an average hourly wage, and press the start button for the clock to start ticking on the cost of the meeting.
Wonder whether there is a clock which can measure the level of restlessness (or declining attention spans) among participants (using camera-based sensors) and trigger the closure of meetings when it crosses a threshold?
