I wholly agree. If you measure efficiency by code production and feature/bugfix turnaround time, I guarantee you can lose a huge percentage of your efficiency very easily. How about a 15 second interruption every 10 minutes? The amount of useful work you got done that day might be well below 50% of an "undistracted" day.

The overhead of constant context switching has a high price. If this is happening on your team, no tool can fix it. You have to fix the culture, and that's much harder.
