Over on The Big Think, 37Signals co-founder Jason Fried has posted an interesting short video about how the modern workplace is designed to provide constant interruptions (phone calls, meetings, colleagues dropping by your desk), and how that’s a real productivity killer:

Fried says that project management tools, IM, collaboration apps and email can be used to reduce those constant interruptions, because if you’re busy you can put them to one side until you have time to deal with them.

Love the part with managers being the biggest productivity killers as their whole world is built around interruptions.
