Abstract:

Recently, I was waiting for a meeting to begin at a 500-person professional services firm. An item on the bulletin board caught my eye. It was a memo from the CFO. If everyone in the firm could spend an hour less per day managing e-mail, he said, it would make a difference of US$2 million a year to the company.
