Improved productivity...

Microsoft has the power to increase global corporate efficiency by a single change to Outlook. Change the default meeting times to 20 minutes instead of 30 min. Make the new standard for meetings 20-40-60 bet we could all get the same done in a 20 min meeting as we do in a 30 min meeting the same for 40 versus 60.

Of course this would not stop the creation of more meetings....
