It's interesting.<p>We consistently see the "multi-tasking makes you stupid" fact from psychologists get attention every so often.<p>On the other hand, a high percentage of job listings, whether it be for a short-order cook or a software tester, or most jobs state something to the effect that they want a "good multi-tasker".<p>The reality is that we often have to wait for things to happen, for instance that short order cook might wait 90 seconds for something to heat up, or I might phone in a request to a vendor and take a few days to get resolution. Practically you have to stack up a few tasks to keep yourself at high utilization, but you have to limit the entry of new tasks to keep your utilization well under 100%.<p>Kanban methods are good for that. You don't let new work in until some old work is done.
