Email interruptions comprise a significant portion of a worker's daily interruptions, with some workers receiving as many as 200 to 300 Email interruptions a day.
Knowledge workers typically work on a task for only three minutes before being interrupted, with typical interruptions including e-mails, phone calls, text messages, and (of course) those pesky co-workers.
According to interruption research, Email interruptions are composed of three stages:
- Switching – Time to switch to the new task
- Processing – Time to process the new task
- Resumption – Time to resume the original task
Interruptions result in:
- loss of memory accuracy
- decreased decision accuracy
- increased decision time for the interrupted task
- Omissions (forgetting) and errors (distortions) of the original task
Research has found that the average time to recover from an Email interruption is approximately 65 seconds. So for someone receiving 100 Emails a day, approximately two hours a day is lost in Email interruption recovery time alone.
The average Email session lasts for 47 seconds, so when you factor in both the Email interruption time and the e-mail distraction time, the result is that workers spend an average of two to four hours per day processing Email, accounting for 25% to 50% of their daily time.
And in an eight-hour workday, 100 Emails a day results in an interruption nearly every five minutes if Email is continually monitored, as is done by most workers.
So what are some of the suggested approaches to deal with the impact of these constant interruptions?
- "Set defined timesto review new Email messages.
- Avoid getting side-tracked and stay focused on important work.
- Don't respond immediately to Email messages, except if critical issues.
- Eliminate notifications for new Email messages
- Reduce irrelevant and non-essential Emails.
- Reduce the quantity of incoming Email message
So make the personal choice to stay focused, eliminate distractions, and process e-mail as just another one of your scheduled work activities.
And remember, you "get less if you send less"!
