The Myth Of Multitasking (Dave Crenshaw)

The Myth Of Multitasking

You're in the middle of working on a project due the next day. At the same time, you have multiple browsers open on your computer while your phone notifications going off. To top that off, you have a colleague who stops by to chat- you decide to talk and type on your computer. Or even worst, you chat with your colleague, working on your computer with one hand and texting on your phone with the other side. Does this sound efficient? In the era of technology and social media, many people buy the myth of multitasking because it sounds very convenient if we want to get more done doing a bunch of tasks all at once.

Not only are you working on a bunch of tasks all at once, but you are working on a more critical task while tackling smaller tasks. These are some questions addressed in Dave Crenshaw's book, The Myth of Multitasking: How “Doing It All” Gets Nothing Done. This book breaks down the false belief of multitasking as a neat way to get more things done. In this article, I will discuss four main takeaways from the book and wrap up with showing you an example I tried out to see if multitasking works or not. The four points include:

1.) Switchtasking, Not Multitasking

2.) Switchtasking Not Effective

3.) Scheduling Recurring Meetings

4.) Setting A Model To Employees Over Forcing Change

The Myth of Multitasking: Switchtasking (Active & Passive), Not Multitasking

The Myth Of Multitasking

Crenshaw brings up the idea of multitasking as a traditional approach in the past, but times have changed in the era of technology and social media. Whether they are smartphones, tablets, or going on social media sites, these serve as huge distractions; therefore, making it more challenging to get more done in less time. Moreover, multitasking is a lie, and Crenshaw says that this is more known as switchtasking. Switchtasking is no better; it is still inefficient and an inadequate way of getting more things done. There are types of switchtasking:

Active Switchtasking

This takes place in a situation you create yourself. A typical example of this would be talking on the phone while checking your email.

Passive Switchtasking

This takes place in situations created by something or someone else. For instance, you are working on a project with the deadline approaching, only find yourself interrupted by a colleague who stops by and wants to chit-chat with you.

The Myth Of Multitasking: Switchtasking Not As Effective

The Myth Of Multitasking

Switchtasking may be necessary for some jobs, but overall it is not sufficient for increasing productivity. Crenshaw gives an example of a CEO of a local retail company. The CEO usually faces interruptions every hour each day, so it's become a regular thing for her to encounter. When a colleague stops by, she types on the computer while talking to her at the same time. However, if the CEO asks questions requiring more thoughtful responses, she may have to stop what she is doing to think over the items carefully. That may not seem like a big deal, but once she returns to her task, it'll take a few minutes to regain the focus she had earlier. So she lost time, even if it was a couple minutes or so.

The Myth Of Multitasking: Schedule Recurring Meetings

One of the biggest obstacles in the workplace is people aren't so sure when is the best time to chat with somebody else. One solution Crenshaw suggests is to schedule recurring meetings with those you need to meet regularly. By scheduling these meetings, you will get more uninterrupted time to get your most important work done.

On another point, it's good to let people know what times of the day you are available to speak with them. For example, some managers will post office hours at their desks, indicating those hours when they are free. Also, it's useful to set up your voicemail and email messaging systems in a similar approach as well. So, if you have people who reach you via phone throughout the day, you can state in your voicemail what times of the day you check messages. The same guideline applies for email- let others know when you look over and respond to an email so that they can get an idea when you respond to their emails.

The Myth Of Multitasking: Be A Model To Your Employees

Crenshaw talks about how you can schedule a meeting, letting everyone know to stop switchtasking moving forward. Instead, use yourself as a model to implement a new type of system at your company. Your example shows to your employees that focusing on one task is much more effective. From there, you can explain to employees how inefficient switchtasking can be and how it takes more time away from your priorities.

Additionally, Crenshaw discusses how establishing a personal system can create meaningful change in your company. Not only can it change the culture, but it will make your business more efficient, an increase in employee productivity, and of course, bring in more clients and revenue down the road. These are the long term impacts that business owners and CEO aim to achieve in growing their companies. Now your model doesn't have to be followed by your employees; however, it can serve as a foundation for others to set up their models. Everyone doesn't need to act the same way, but whatever model they practice and work best for them, they should stick with it.


In summary, multitasking is no longer useful and considered a thing of the past. It may have worked before. Still, in the advent of the digital era, multitasking is irrelevant, with more distractions present in the 21st century. As Crenshaw mentioned, a common practice today is known as switchtasking- going back and forth in completing tasks at once. Multitasking or switchtasking, both terms sound similar.

One final point from the book: I did an example to determine how productive multitasking is. So I wrote down the following sentence: “Multitasking Drains Time.” So I wrote it out, beginning with each letter followed by a number afterward. From what I wrote down, this took me much longer to do instead of writing just the sentence alone.

Here's a look:

Writing this out took me much longer than I thought! Doing this task is one example of why multitasking isn't practical. Try doing the same thing, and see what you think.

  1. This information will be helpful to me in the future as I am setting out in this new business venture. I’ve looked into the problem of multitasking but this spells it out way better than I could have thought. Very great work on this sir and will remember in the future.

    Thank you

  2. Thank you for sharing this information. I always though multi-tasking was the way to go but I can see with your exercise of writing the the sentence, the multi-taking actually drains productivity. Concise and informative.

  3. Hi,
    Thanks for this article, I am just discovering for myself that multi tasking doesn’t really work any more.

    I work from home on my laptop and the opportunities for multi tasking once my computer is open are endless.

    The only way to get any real work done is to focus on one task and that alone.

    I don’t have meetings to schedule, but I’ve taken your advice and informed the people around me of the time I can be spoken to, and when I’m working and unavailable.

    I can’t believe I didn’t think of that before!

    Thanks again,


    I don

  4. Hi, this was a great article to read. I really like that you included the visual example at the end of you multitasking. I’ve been aware for a while that multitasking is a myth and that when someone says they’re good at multitasking what they really mean is they’re good at transitioning quickly between two things, however I didn’t know until I read this that it is called switchtasking, fascinating! I like the YouTube video you included at the end as well, nice touch. Very thorough and visually engaging!

    • Thanks, Natalie. I learned quite a bit about reading Crenshaw’s book, such as identifying the term “switchtasking”. Glad you liked watching the video, I plan on doing more videos when I write product reviews.
