Do you realise that one silent productivity drainer today is technology? Now, do not get me wrong. This has nothing to do with technology itself, but has everything to do with how we use technology.
Consider this: Most knowledge workers lose about two hours of their productive day to constant interruptions.
It is not the interruption itself, which might be intermittent and very brief that is the issue. Nor is it the method of delivery. The problem is the recovery time.
It can take a considerable amount of time to get back the train of thought we had before the interruption occurred. Sometimes, a crucial aspect of the thought process might even be forgotten and lost forever.
Typically, it will take 10 to 20 times the length of the interruption time before we can refocus (and that is if we are not interrupted again.
