"Being productive isn't something that just happens. You don't just sit down and be productive. Real productivity takes time. It's a process. You make your way into it. Sometimes it takes 15 minutes or a half hour or an hour or more to really get in that zone. And when you're in that zone you are actually getting real work done. But once you get knocked out of that zone it takes a real toll on you. You go from highly productive to annoyed."
Gotta keep in that flow zone for real productivity.
In a related manner, and getting above the issue of interruptions a notch or two, one of the roles of an effective enterprise multi-project management process is to provide clear prioriy to people regarding which task they should be focused on, letting them set aside lower priority tasks with no guilt or pressure to multi-task (interrupt) with them.
