Anecdotally, people were reporting they were crushed by all of these different projects. Peoples lives as information workers involve different kinds of technologies, and they create even more of a force for interruption and different places where we can focus our attention. Is this the downside of the communications revolution Interruptions arent necessarily all bad. People report that some interruptions can be beneficial. The downside is the stress that comes from switching topics so rapidly throughout the workday. How often is the modern office worker interrupted We had observers go into the workplace and we timed peoples activities to the second. Weve been to various workplaces, all high tech companies. We wanted to look at information workers. We had observers shadow each person for three and a half days each and timed every activity to the second. If they pick up a phone call, thats the start time. When they put the phone down, thats the stop time. When they turn to the Word application we get the start time and stop time. We found people switched these activities on average of every three minutes and five seconds.

For no apparent reason, the person picks up the phone and makes a call or starts surfing the Web. When is interruption beneficial If an interruption matches the topic of the current task at hand, then its beneficial. If youre working on task A and somebody comes in and interrupts you about exactly that task people report thats very positive and helps them think about task A. Theres been a lot of research into the psychology of problem solving that says if you let problems incubate, sometimes it helps in solving them. A good example would be a software developer who just cant trace a bug so they put it aside and let it incubate. The answer may come back to the software developer later while he or she is working on another task. This is an example of how switching tasks may be beneficial. If interruptions are short theyre usually not so bad. Imagine youre working on this article and some one comes in and says, Here, can you sign this form You sign it, its a very subordinate kind of task and you go back to doing your work. Any kind of automatic task that doesnt require a lot of thinking would not be a major disruption. When is interruption counterproductive Its generally counterproductive if youre working on one task and youre interrupted on a completely different topic. People have to shift their cognitive resources, or attentional resources, to a completely different topic. You have to completely shift your thinking, it takes you a while to get into it and it takes you a while to get back and remember where you were. You also found that people not only switched between small tasks but also between entire projects a phone call and e mail on one project, then jumping to a completely different topic. We figured, maybe its not so bad to switch activities within the same theme. We clustered events a phone call, a Word document into similar contexts that we called working spheres. We found that people switched those every 1. Say youre a financial analyst working on the TX project, then the BC project, then planning the company picnic and then going back and work on this original TX project. Do you believe this behavior is typical of knowledge workers Yes. These were people who were managers, financial analysts, software developers. The only significant difference we found due to profession was that software developers spent a little bit more time on the PC before switching. But its not even that much time something like four minutes as opposed to three minutes. Other than that, we found no significant differences among professions. How long does it take people to get back on task We found about 8. But heres the bad news it takes an average of 2. What are the psychological costs of all this switching We found there is significantly more stress. We did a laboratory experiment where people did a typical office task they had to answer a set of e mail. In one condition, they were not interrupted. In another condition, we interrupted them with phone calls and IM. We used a NASA workload scale, which measures various dimensions of stress, and we found that people scored significantly higher when interrupted. They had higher levels of stress, frustration, mental effort, feeling of time pressure and mental workload. So thats the cost. There was no significant difference in number of errors between those who were interrupted and those who were not. But Ill tell you something very interesting that we found when people were not interrupted they worked slower. Heres how we interpret that when people know they can expect interruption they get into a mode of working faster to compensate. You know youre going to be continually interrupted so you compensate by working faster, but the cost of that is stress. How do you explain the stress Its a feeling of just not being able to keep up. There was very high powered lawyer on the east coast who told me that every Sunday morning he wakes up before the rest of his family, clears off the dining room table, lays out all his casework and spends the entire Sunday just catching up on what he wasnt able to complete during the week. Thats another dimension the inability to just get away from work and take a break. Its what I call invisible work the work that your colleagues and managers dont see, the extra work you have to get done just to keep up with the demands of the workplace. Are we becoming more superficial thinkers I argue that when people are switching contexts every 1. Theres no way people can achieve flow. When I write a research article, it takes me a couple of hours before I can even begin to think creatively. If I was switching every 1. Id be able to think deeply about what Im doing. This is really bad for innovation. When youre on the treadmill like this, its just not possible to achieve flow. But many people tout the information revolution as a great spawning ground for creativity were coming into contact with new ideas, forging new connections, tapping into new networks. Do you buy any of that You have to put that in perspective. Let me give you an example. Eleven years ago I was a researcher at the Boeing company I studied a virtual world that was being deployed so people in the distributed company of Boeing would be able to meet others share expertise. It was basically like Second Life. We deployed this and we could not get anyone to use it. They went there out of curiosity and then they left and never came back. Eleven years later with Second Life, with all due respect, were seeing exactly the same thing. People come, theyre curious and then they dont come back.
