Find out how long it takes to re-focus when a co-worker interrupts
According to a study out of Carnegie Mellon University in Pittsburgh, every time your coworkers talk to you and distract you, you immediately become 20% more distracted.
A separate study found the average officer worker only gets 11 minutes of work done between interruptions and it can take almost half an hour to fully focus again after you're interrupted.
The researchers at Carnegie Mellon did find the best defense. If you tell yourself you're definitely going to be interrupted at any moment, it actually helps you focus and improves your productivity.
