Slashdot Asks: How Do You Handle Interruptions At Work? 224

This question was inspired by this anonymous submission: Analysis of programming sessions and surveys note that programmers take 10-15 minutes to resume editing code after being interrupted. Computer scientists and researchers from University of Zurich and ABB Inc. have designed the 'FlowLight' system which automatically determines a worker's interruptibility using a combination of keyboard/mouse usage, calendar information, and login state, and makes interruptibility visible to other employees using a red/yellow/green LED indicator placed near the desk... Knowledge workers in various locations found that interruptions were significantly reduced by 46%. [PDF]
NBC reports these researchers "also tested a more advanced version that uses biometric sensors to detect heart rate variability, pupil dilation, eye blinks or even brainwave activity," and of course one of the researchers tells the New Yorker that a commercial version "is 'in the works.'" But it'd be interesting to hear from Slashdot's readers about their own solutions -- and how interruptions affect their own productivity at work. So share your best answers in the comments. How do you feel about interrupt

    I understand this is for coders, and how someone might think that when they don't tap away angrily they are available for interruption, but it would be safer to assume that when tapping slows or stops, there's a reason for that. And that reason might not always be that they have nothing more to do. Researching stuff, reading stuff, and just thinking about stuff might not be done in parallel with mighty mouse movements and constant tapping, but they are equally important. So my opinion about this is that it's a result based on research that just wasted money. The simplest way is generally better: just ask, or even better just agree on a time to discuss issues, it's really not rocket science.
    • I understand this is for coders...

      Not really. If it were for coders it would be discussing how to mask out irrelevant interrupts and install a suitable interrupt handler to deal with non-maskable interrupts.

        Because that interruption might be from the guy who signs your paychecks.

        For me, it isn't coding, but 3-D work. It's like an alternate universe, and while reducing everything to numbers and juggling it all in my head, I do lose track of reality. And it takes time to come back, then get into the 3-D Universe again.

Strangely, the article mentions that manual actions such as turning on a red light, putting up a sign, wearing headphones or closing the door to the office were perceived as "too cumbersome".

      This has never saved me. I monitor how long it takes from putting on the headphones to be interrupted. Far too often, it's less than 60 seconds. The virtually unbeatable record stands at zero seconds. Every now and then I can work without being interrupted, but having my headphones on doesn't seem to stop anyone. I wish they would use the internal IM system! Much less distracting.

      In my office, Green would be "I'm OK to be bothered right now". Lots of times, this would be if I'm waiting for a meeting, not doing programming, etc. Yellow is "Don't bother, unless it is absolutely necessary". For example, when there is a blocker issue or something that does require my attention, but not chit-chat. Red is "Don't bother me unless the building is on fire". This is when I'm really trying to concentrate on something and really can't be bothered for any reason.

    Looking at it from a manager's perspective:

    Work in rooms, not an open-plan office. This way, if someone wants to interrupt you, they have to "pay" a higher price, like messaging you (you may not be available or the nature of the asynchronous conversation may not be convenient) or actually getting up and going to your room.

    Cultivate a culture of empathy, wherein people learn to pick up signs that someone is busy working. Apply peer pressure when someone doesn't pick up the cues. Make it an "insult" to destroy someone's flow. Don't be a dick about it, though - there are ways of cultivating this slowly and discreetly.

      Someone in the ops dept in another company I worked at used to do that. In the end we just resorted to visiting his desk on the next floor up. He didn't like it but (unlike a coder) part of his job was being available for internal support issues so he couldn't complain. He wasn't overworked , just lazy. Whenever you went up (and he didn't spot you coming) he'd just be surfing the web.

      • Thankfully, I am not in operations so I don't have to be available all the time. :D But I have deadlines to meet so sometimes I have to isolate myself for a few days.

        But it seems like when you are too available, people seems to ask for help alle the time for something they could figure out if they would spend 3 minutes on it.

      That's a nice theory, but the problem is that many managers will ding you on reviews for poor time management. I've known people who got fired for it, being told that part of what was expected out of them was the ability to judge conflicting workloads and prioritize them yourself.

        Exactly. And people who cannot be interrupted are not as valuable as those who can time manage.

        The dirty little secret of the monotaskers is that their insistence on one task, and one task only is as likely to be based on screwing off as it is on concentration.

        But these days, asking what your number 1 priority is almost always results in "they all are number 1" and nobody cares to fix this.

        I have shown people the workload, with everyone insisting that their job was "top priority", and saying that I had to figure out somewhere to start working first, so perhaps alphabetically would work for them? Especially if their name was "asshole"

          I've used that technique before. Mostly gently, and people understood immediately that they were outranked by Bob so he got his first.

          But there were times where it was still true, but people didn't like the answer and I had to be really blunt. "If I don't do Bob's first, I get fired. If I don't do your job first, all that happens is you get mad. Do you understand why Bob is my priority and you aren't?"

          The second role is to actually *do* a fraction of the work. Either because *their* managers deem it too sensitive to be delegated to rank and file employees, even if it is what they do best, or because they don't have enough rank and file empl

    I have a cash acceptor wired up outside my office, which dispenses sequential tickets. I won't talk to you unless you have a ticket.

    It was kinda a stupid joke I setup one day because I got sick and tired of being constantly interrupted. People actually took it seriously, much to the amusement of my boss. The first day I made well over $120 in spare cash from all the interruptions. The next day, I only made $40, but got so much more work done. The day after that, it was around $10, and then finally people got the hint and it was $0.

    Occasionally someone still comes and knocks on my door, and for the privilege of interrupting me, they get to pay $10 (in cash or coins). If I'm not too busy I'll drag the machine inside and leave it unhooked, but otherwise it's out there by my (closed) door and plugged in, ready to accept payment. I even landed up building an additional three units for our other developers (it's basically just a laser cut plexiglass chassis with an Atmel AVR development board, an OTS cash acceptor, and an OTS ticket printer). Our productivity has skyrocketed as a result, and management even lets us keep the cash we make. Most of the time, it gets reinvested back into the office as donuts or other treats though, so it's not like we're actually making a massive profit or anything.

For instance, right now, even with headphones on, I can hear and feel the movement of people around me. There are conversations and distractions happening out of the corner of my eye.

    Since I can't control the environment much, I control me as much as I can. If working from home is a possibility, I do that as of

  • The further you go in your career - development lead, architect, etc. the interruptions only increase. The time you have for productive coding will drop to near zero unless you explicitly make the time. But yet if you stop coding, you will not be as familiar as you need to be with your domain. Here are some strategies that may help:
    * Schedule 1:1 meetings with yourself in a different area than you normally work. Be disciplined and use the time only for coding.
    * Come in earlier than anyone else. I f
