Does Multitasking Actually Boost Our Productivity?

Multitasking. A word often thrown around by bosses and management gurus when they want their hapless teams to increase their productivity. But does it really help in getting things done the same way had you approached them sequentially? Design and interface expert Aza Raskin has a different take. He says it is near impossible to think about two things simultaneously, which means we cannot truly multitask things. When we do achieve two tasks at the same time, its because one of them is automatic, that is, we are habituated to it.
