EMAIL or EFAIL: How Big Is Your Inbox?
By joesciallo on Jul 31, 2008
According to a report to be published in October by the New York-based research firm Basex, interruptions such as spam, other unnecessary e-mail and instant-messages take up 28% of the average knowledge worker's day.
On top of that is what Basex chief analyst Jonathan Spira refers to as recovery time -- the time to get back to where you were before you were interrupted, which Spira says is 10 to 20 times the duration of the interruption. These interruptions account for up to 2.1 hours per worker per day. Multiply that by 56 million knowledge workers in the U.S., he calculates, and the cost is $650 billion per year.
