Multitasking Harmful To Productivity
Greyfox writes: "According to a CNN article, a person who is multitasking several things takes a hit on his productivity. Oddly enough, it reads almost exactly like a description of the problem with multitasking on computers; context switches cost, especially if you have to swap a lot of crap out in order to fit the new process into memory. So basically, an employee who can stay focussed on one thing for long periods of time is going to have higher productivity than one who has to handle constant interrupts. Now if I could get my manager to buy into that ..."

That'd be real-time multitasking.
There's a running joe that James' century old work represents basically everything cognitive scientists know today. In other words, not much new progress in the last 100 years. :) Anyways, to quote from James' book, chapter 11 (emphasis mine):
[p. 409] If, then, by the original question, how many ideas or things can we attend to at once, be meant how many entirely disconnected systems or processes of conception can go on simultaneously, the answer is, not easily more than one, unless the processes are very habitual; but then two, or even three, without very much oscillation of the attention. Where, however, the processes are less automatic, as in the story of Julius Caesar dictating four letters whilst he writes a fifth,[9] there must be a rapid oscillation of the mind from one to the next, and no consequent gain of time. Within any one of the systems the parts may be numberless, but we attend to them collectively when we conceive the whole which they form.
When the things to be attended to are small sensations, and when the effort is to be exact in noting them, it is found that attention to one interferes a good deal with the perception of the other. A good deal of fine work has been done in this field, of which I must give some account.
It has long been noticed, when expectant attention is concentrated upon one of two sensations, that the other one is apt to be displaced from consciousness for a moment and to appear subsequent; although in reality the two may have been contemporaneous events...

I haven't done any formal XP projects but I've certainly had the experience of developing code alongside another person, and found it works very well.
A discussion of "multitasking for programmers" and why it hurts is at Distraction: the one big obstacle. This is written for programmers, but it is true for everbyody who works with knowledge.

I can't. I have CAPD(Central Audiotory Processing Disorder). I could spit it out, if I knew what he was asking, but that's what I can't do, make sense of what I hear. If I'm doing ANYTHING else, I don't understand what somebody is saying to me, be it hitting something with a hammer, reading a book, coding, looking at a wall, if my attention is even remotely used for something else, I can't hear people.
That includes thinking of what to say when they're done talking, or if they get me thinking of something else. It's really annoying, actually. That's why I can't do the phone-monkey thing.It does have its advantages, though. I'm not easily interrupted when doing work, I don't hear people talking to me when I don't want to, it's not ignoring, it's involentary, but convenient at times. I have not trouble visiting my own little world.

One new age, diversity celebrating, politically correct company chick asked me, from her list of prepared questions, "Do you believe you multitask well?" So, I asked her, "Can you define multitask, so I can be sure I'm answering the question you want answered?"
"Doing more than one job at a time", she replied, "like debugging one minute, explaining an important process change to a coworker the next, and then going back to debugging." I thought on this for a moment, wondering if it was a trick question, an honest question, or perhaps an honest question that through the acts of self deception and corporate mind-fucking had become a trick question. So I figured I'd just be honest, and let the chips fall where they may. "No, I do not believe that I multitask well in environments such as this, and in fact I do not believe that anyone multitasks well in an environment such as this. When I worked at Burger King, as a teenager, I could make fries and fill drinks at the same time, but those were not mentally challenging tasks."
"I happen to think that I multitask very well, and don't find that it's all that difficult", she said to me. And it was at that very moment that I realized that I was not meant to work in the corporate environment. Which is fortunate, because I did not get that job, and I'm still self-employed. The PC company chick? She proved that she multitasked well by volunteering for every function that would keep her in meetings, all day every day, and for avoiding work so skillfully, but being seen rushing past on her way from one conference room to the next, she was promoted and now runs the department.
My point? There is a fallacy floating around in corporate America, that in order to produce more output with less time and fewer resources, we must all fill many roles. Instead of focusing on doing one job very, very well, we are supposed to compensate for the fact that jobs have been eliminated, but their roles have not. So we are expected to "multitask" -- and the harder we're expected to swap, the lower the work output, the lower the quality of it. We are never allowed to operate at our full potential because we cannot achieve the mental state necessary to do Great Work. We find ourselves staring at the same problem for half the day, only to spot it within 20 minutes first thing the next morning, before our minds are cluttered up with corporate crap.
Productivity and quality will not improve no matter how many policy changes and process controls we are subjected to. What has to change is the production budget has to rise in direct proportion to shareholder dividend reductions. We are not going to cure anorexia by starving it to death!
Being self employed, I no longer have to deal with the down-sized company (or being down-sized out of a job) and can focus on my work as long as the telephone doesn't ring. It always seems to be that client with the hairiest project who calls right at that moment when the feeling of an inspiration forming is building... and I let my wife answer the call and take a message. Gotta love it.

I often have half a dozen (or more) things going on at once, switching between screens, applications,
and even computers regularly.
Why?
Because I'm *waiting* for things to happen. Waiting for that 3 minute web page to load,
waiting for that 10 minute compile, waiting for a reply to an ICQ, or whatever.
If I couldn't multitask, I'd be sitting dumbly staring at the screen waiting for whatever task I'm doing to
become ready for my input again.
Sure, a lot of time/energy goes in the context switch. But it's time that's wasted *anyway*.

I think I have the same problem although it sounds less acute. When my wife talks to me I can't hear her. The disorder seems to be hereditary because my kids can't seem to watch tv and hear their parents either...
It should be common knowlege, except management doesn't often seem to make the connection between reality and most management books. There's a great book The One Minute Manager Meets the Monkey all about deligating tasks to reduce the mmanager's stress level and allow him to focus. Unfortunately, This book alocates vary little time to task assignment across staff, such that your staff can focus on a limited number of tasks in an organized sequence. This is unfortunate since the productivity of a manager doesn't often ralate as directly as we'd all like to believe; to the productivity of his employees.
