Since I became technical coach, I get interrupted all the time. Being this by mails, colleagues or your boss. The pomodoro technique should help your productivity.
The technique basically lets you work in uninterrupted blocks of 25 minutes and gives you 5 minutes to handle any diverted interruptions. Note that this does not mean you can ignore everyone and can just start using the technique without informing your colleagues.
I will give the pododoro technique a test next week. I will evaluate if I got more work done and ask my colleagues how they feel about the approach.
