Debunking The Myth of Multitasking
Posted by Gina Trapani at 9:00 PM on August 25, 2008
In a fast-paced business culture of "get everything done yesterday," it's easy to admire and reward those busybusy people who always seem to be juggling 14 things at once. But business coach Dave Crenshaw argues that the most common kind of multitasking doesn't boost productivity—it slows you down. In his new book, The Myth of Multitasking: How "Doing It All" Gets Nothing Done, Crenshaw explains the difference between "background tasking"—like watching TV while exercising—and "switchtasking," juggling two tasks by refocusing your attention back and forth between them, and losing time and progress in the switch. Crenshaw's on a mission to reduce distractions, interruptions, and fire-fighting at work, and create environments that let employees see through tasks with their full attention before moving onto the next thing. Here's what Crenshaw had to say when I asked him a few questions about changing perceptions and habits around multitasking. Photo by Elsie esq..
Lifehacker: People who have done any kind of reading about personal productivity already know that there's a high cost involved in switching from task to task during your workday. But knowing something intellectually and making changes in your routine to reduce "switchtasking" are two different things. What do you think has to happen for folks used to switchtasking to actually make the changes to their regular routine?
Dave Crenshaw: Switchtasking is a largely cultural problem. I've found that most people actually still believe that multitasking is a productive activity. It is culturally acceptable to switchtask. Smoking is on the decline in the U.S. because it has become less culturally acceptable. As multitasking becomes more and more of culturally unacceptable behaviour, people will makes changes.
However, I find that the best way for people to ultimately make a lasting change is through one-on-one training or therapy. It is a big part why I created the TimeGym program. The worksheets in the book are also helpful because they help readers experience the impact of their own personal switchtasking.
Lifehacker: Many mid-level employees today work in an open office layout without their own office or even cubicle—their desk is just out in the middle of the floor with everyone else's. When you work in this kind of setup, often you're expected to attend to interruptions as they happen. Co-workers stop by your desk to ask a question, you get pulled into a conversation happening two desks down, there's an culture of a quick turnaround on email messages and constant monitoring of the inbox... how can someone who's not an exec or in management reduce their switchtasking without looking like a slacker? Do you run the risk of looking less responsive?
Dave Crenshaw: The situations you are describing really are a huge drain on productivity. It is very difficult for someone in a middle-management or "front line" position to change that kind of environment. Ultimately, a business or an organisation is a reflection of its leader. The leader has to make personal changes before an organisation as a whole can improve productivity systems. If not, the leader will constantly undermine any systemic improvements.
I can offer a couple of suggestions. First: see if you can set up recurring meetings with the people who are interrupting you. In my experience working with people, establishing a recurring meeting at a set place and time is like magic, and it really does cut down on a huge number of interruptions very quickly.
Second: find a way for the leadership of your organisation to pay attention to the impact of switches in the workplace. A few people have commented that they are going to give the book as a gift to their boss because it presents the issue in a casual, non-threatening way.
Lifehacker: Do you think companies are getting better or worse at creating environments that discourage switchtasking?
Dave Crenshaw: I think we are at the beginning of a very long process of change. The large companies working on the problem are only in the very preliminary stages of attacking this issue. Most small businesses aren't even aware of the source of the problem. In general, companies recognise they have productivity issues, but are unsure as to how to proceed. Awareness is increasing, however. Over the next decade I expect we'll see a lot more attention on this issue and a great deal of improvement.
Lifehacker: You've said that technology isn't the reason why we switchtask more, it's the way we use it that's the issue. However, turning off technology (like silencing your ringer or closing down your email inbox) is one of the best ways to focus on something. What do you think about the approach taken by guys like Don Knuth, the computer science author who has eschewed email entirely in order to write books? Or folks who opt out of getting the BlackBerry or Treo because they don't want to deal with the expectations it comes with? Is purposefully refraining from using certain kind of technology extremist, or evolved?
Dave Crenshaw: This is a bit like an amateur carpenter, who, after hitting his thumb with his hammer, curses the tool and tosses it aside. Was the pain caused by the tool, or by the lack of skill of the person using the tool?
A big part of how we use technology comes down to the big WHEN. Shutting technology off completely certainly is not the answer just as it wouldn't be the answer to try to use a rock or your hands to put nails in boards. What we need is more skill training and development. For instance, I know Lifehacker advocates the principle of "firewalling" one's attention. That's a great skill. It helps minimise switches. There are many, many of these new skills that we need to acquire. They have become essential not only to our productivity but to our mental and emotional survival.
Finally, Crenshaw offers a few tips for reducing switchtasking and making better use of your time.
Take control over technology—Your mobile phone ringer (even on vibrate) doesn't need to be on all the time. You can turn off email notification on your computer as well. Become master over the nagging beeps and buzzes by creating some silence.
Schedule what you can schedule—Set regular times in the day and week to check your voicemail and email. Let others know that you will be using that schedule so they know when to expect a reply.
Focus on the person—When you switchtask when dealing with a computer, you simply lose efficiency. But if you switchtask on a human being, you additionally damage a relationship. Be present, listen carefully, and make sure everything has been taken care of before moving on.
Is your office a hotbed of switchtasking or do you have the time and space to focus on what you need to get done without an interruption in the next 10 minutes? Are you constantly scanning your inbox or handheld for new messages when you should be writing that report or crunching those numbers? Tell us what you think about multitasking in today's office in the comments.

Usually when I'm jumping back and forth between programs on my computer, it's because I'm waiting for something in another. Other than that, I actually agree. I've had to learn to control my adult ADHD, which has proven to me quite a bit that working on too many tasks at once just makes it so none of them get done.

I've fully recognized the need for #3, to focus on the person. To actually let go of the mouse and turn my body (not my head) makes an enormous difference in what I can get out of a conversation with someone.

Hmm, I wonder if listening to the radio decreases productivity as well. There's always music playing over here, so it would be a big deal to us if it does.

A great article and topic. I have started coming into my office an hour early and setting that time aside for cleaning out my inbox and setting a list of tasks for the day. Once I have a clearly defined list it really helps in taking them one by one until they are done.

In my work environment (I'm a professor) colleagues stop by all the time, but even though it's an interruption in work, the political payoff to speaking with them as if you have all the time in the world is well worth it.

Debunking the myths of multitasking? I think you mean "exposing" rather than "debunking," unless you think Dave Crenshaw is wrong. Also, just to be extra persnickety: the title of his book is The Myth of Multitasking, singular, so when you refer to "the myths of multitasking" you shouldn't be italicizing that phrase.

How much of the "Multitasking" craze is due to the "do more with less" philosophy, or due to "budget cuts?" It seems that whenever I am assigned new items, these two phrases alway come up. I floored an interviewer once by asking their definition of multitasking and why it was a necessary ability for the position. Surprisingly, I did not get a real good answer.
Glad to see that someone (finally!) points out that the skill level of the employee has to be taken into consideration when issuing technology and managing expectations. I would be interesting to see a study on the knowledge base of the everyday user-and I'm not referring to blackberry/treo's-I'm talking about the basics: Outlook/email management and the basics of MS Office. You would be surprised how many times I can amaze people by setting up folders in their Outlook inbox or crating a macro in Excel.

I work in one of those "open office layouts' and yes co-workers often stop by my desk to ask a question ( although I am guilty of that as well ). Sometimes I go home and I wonder "What the *** did I do today".
The one thing I do control is the email inbox. I am using Zero Inbox principles ( reading my email only at specific times of the day ) and that has improved my productivity. Except for the co-workers who come by to ask "Did you get my email?".

Sometimes it's important get that phone call or that e-mail. Think of all the miss opportunities you'll have.

I'm with @micjwelch in that I switch while waiting for something else to load/process. At home, background tasking not only includes TV, but listening to podcasts too.
I still think people don't understand *when* email is appropriate or necessary. The expectation that it'll be read/replied to immediately is absurd.

My family got used to me being the one-stop-shop for all kinds of information. Everything from "Where's my coat" to "When's my parents' anniversary." During the days when I was working at home and with deadlines, the constant interruptions drove me berserk. I had no place I could go and shut the door (perils of small income and smaller apartment). The fact that I could answer their questions while I was working didn't mean I wanted to do it.
I finally threw a screaming fit at one too many interruptions for a question the answer to which was "If I wasn't sitting here you could figure that out by yourself just fine." I laid down the law. If I'm typing, I'm busy, and you do NOT interrupt me unless the house is on fire or someone's spurting arterial blood on the rug.
That worked well enough. Now I've got a home office where I can shut the door, and my husband's starting to inch back into the habit of asking me questions while I'm working. Maybe I should get a padlock.

This weekend I did some major conquering of the productivity-hampering switchtasking. I've been trying to write a term paper for the past weeks with no success, and managed to churn out a solid 23 pages in the past 3 days.
How'd I do it? Freedom!

@Protector one: It does if you want to throttle everyone at whatever station's playing, from upper management down to the receptionist. (Doubly so for being one of those stations where the format's based around people listening to it at work... especially when you can fit the entire playlist, legibly, on a 3x5 index card. Hand-written.)
Although I find myself being able to focus better with Pandora in the background, which might just be because I know it'll be songs I like. Then again, I also tend to be more productive after knocking out a couple of sudokus, especially when I'm paginating and need to worry about how I'm going to fit all my stories in the paper.

That is very true. I've seen people who essentially shun socializing in order to get work done. In the end, noone really knows you they are and it ultimately hurts their career.

I've long called multi-tasking "semi-tasking," but "switch-tasking" also works for me. :-)
In recent years, I've also come to believe (and it appears that Dave Crenshaw just might agree) that the ADD epidemic is as much a cultural problem as it is a biological one.

Now the title of this article (currently "Debunking The Myth of Multitasking") seems to be directly challenging the author's book (and if I were him I'd be annoyed, after giving an exclusive interview). If you support his ideas, remove the italics in your article title so you're not implying you're debunking his book.

By entertaining interruptions, it is an admitted instance of switch-tasking for you; however, you may be relieving the interrupter from switch-tasking in their workflow by providing a vital piece of missing information. It may actually hamper the flow of the collective whole of productivity for the interrupter to have to schedule time later and switch-task their workflow. It is not a black and white situation.

It is well known that some people have a genetic defect that seems to prevents them multitasking effectively. This defect is not at the gene level but at the chromosome level. However, the way it acts is uncertain, as it has been noted that single fathers with custody of their children do manage to acquire the skill fairly quickly and can operate as effectively as women in this regard.
Or in other words, this is yet another skill which shows a big range owing to nature and nurture. Trying to mandate that everyone should conform to the boss's or the guru's pattern of thinking is stupid. And especially stupid if they are managing programmers -- the demands of that job include bearing in mind simultaneously a host of different factors at different levels all constraining what is appropriate code, and brains which handle that well may be able to happily multitask.

I always thought this was great. I know Earl Nightingale and company always talk about the 6 task list. You right down 6 things you have to do tomorrow in order of importance. Then when tomorrow comes you do the first one until it is complete, now working on any others until it is done. Then when the first task is done you move on to the next without worrying about any of the others. Giving your best to each individual task is always a better approach in my opinion. May not work for some but even in my fast paced, "multi tasking" IT job I try to use this philosophy as much as possible!

Switchtasking really IS a problem. Before this post I actually thought it's just MY problem that I can't work when someone speaks, so I'm just the wrong type of person for business. Thank you for explaining that it is a common problem. I will try to find ways to be more focused. I'm right, and the system is wrong. Ya-hoo!

Thanks for the post, Gina!
Lifehacker readers can take a test online to see how well they multitask:

Sounds like a really good book and it's now on my list.
Multitasking is actually impossible, from the evidence presented in neuroscience. John Medina discusses this his recent book, "Brain Rules"

Does this mean I need to turn off my RSS feed for lifehacker in order to get things done? =( Seriously though, I think that there are tradeoffs and advantages to being able to accept interruptions, as long as you are able to transfer your attention to things that have actually higher priority instead of "just anything".

Hi, This should be the workers bible. I had a heavy parallel processing multi-tasking partner. No way to get any answers or anything done. It equates with parallel incompetence (technical or social), you don¹t know what to say or how to do something, switch task. Now for an other subject... JF
