Office Space vs. The Programmer

30. January 2013 02:44 by Troy | 1 Comments

The office is a place to get work done.  Why then, do so many complain they can't get any actual work done while "at work"?  This problem is common among most office bound employees, but I'm most interested in how it affects my field, The Programmer.  Specifically, how does the office space support or hinder the programmers' productivity?

There is no shortage of innovative office spaces out there, each with it's own advantages and disadvantages.  Everything from windowless plain white boxes to funky open concept, natural material spaces that invite the outdoors in and spur the imagination to wander.  When it comes to office space, some characteristics come to mind:

  • comfortable
  • no distractions
  • distractions
  • controlled dimmable light
  • natural light
  • quiet
  • moderate noise, hustle and bustle
  • no interruption
  • interruption and collaboration is great

I believe that all of those are important.  Of course the ones in bold represent the exact opposite of the others, with the exception of being "comfortable".  The reason for this is because my ideal office space depends on what I'm doing.  Programmers are most productive when they can get into "The Zone" where nothing else exists in their mind except what they are working on.  All of the items in bold support the ability to get into "The Zone", while the others usually serve to disrupt or prevent getting into and staying in The Zone.

Comfortable is the easiest item to deal with because it is constant, the need for it doesn't change with the type of work you are doing at that moment.  People always want to be comfortable.  Not being comfortable is a distraction so you want to get this right.  Office temperature and good equipment (desks, chairs and computer hardware) serve the employee and allow productivity.  A worker who is in pain from shoulder fatigue or shivering under a blanket will not do their best work.

The Zone is important for productivity.  Being knocked out of The Zone is costly for the business, because studies show that once a developer drops out of The Zone, it can take at least 10-15 minutes before they can become productive again and get back to where they were at the time of interruption.

Getting back to our office space, lets consider some of our options:

Office TypePromotesGood For The ZoneGood For Collaboration
Open Concept distractions, natural light, moderate noise, collaboration, hustle and bustle No Yes
Cubicles reduced distractions, natural light, moderate noise, reduced hustle and bustle A bit better It Depends
Individual Offices no distractions, controllable light, quiet, no interruption Yes No

So, it looks like we can maximize collaboration or The Zone, but we can't have an office space that is best for both.  Personally, I'm not really a fan of cubicles.  I'm not sure that their cost is worth the little bit of privacy and reduction of visual distraction that they provide.

What is the perfect developer office space?  An article posted on TechCrunch talked about Facebook's Mark Zuckerberg hiring famous architect Frank Gehry to design the ultimate space for employees to get their geek on.  Zuckerberg says: 

The idea is to make the perfect engineering space: one giant room that fits thousands of people, all close enough to collaborate together.

Ok, the largest open floor plan in the world sounds cool, and is something I wouldn't mind seeing, but I don't think my concentration level would ever approach The Zone in a room with thousands of people.  Of course, this level of extreme is beyond the scope of most corporations anyway, but the general idea is the same.  How can the business maximize employees and minimize the floor space needed?  Clearly the Open Concept floor plan wins if that is your primary objective.  Also gaining popularity is Agile Software Development which emphasizes collaboration with an open concept work area called a "bullpen".  It seems that the cards are stacked in favour of the Open Concept design.

Now, Zuckerberg is not oblivious to The Zone.  He also said:

It will be the largest open floor plan in the world, but it will also have plenty of private, quiet spaces as well.

If your devs are not chained to their desks because they use laptops and your building has enough space to create shared, private spaces that workers can move to when they want to find The Zone, that may be one option.  If workstations include multiple monitors, then the private spaces should be likewise equipped for this to be a viable option.  Even then, this solution may not be perfect, as the dev may lose access to visual cues they use when at their desk, like post-it notes, whiteboards, corkboards, etc.

This brings me to the first iteration of what my ideal office space might look like.  This assumes the use of Agile Software Development, which arranges its people in cross-functional teams of around 6 or 8 people.

The image above shows a mock-up floor plan that I think would work well for the following reasons: 

  • one team per office/room is cheaper than separate offices for each
  • collaboration is encouraged by placing team members together, with a center table they can roll up to
  • The Zone is supported by short dividers between desks to reduce visual distractions
  • keeping dividers short, collaboration is supported by allowing teammates to simply lean back in their chair to see each other
  • Agile is supported by whiteboards and/or scrum boards for the team along the bottom wall
  • The Zone is supported by a room with a door to reduce non-team related distractions
  • separating teams in different rooms allows each team to find their own rhythm, without disrupting the other, so one could be in The Zone while the other openly discusses a new feature
  • cross-team collaboration can be facilitated with meetings, or ad-hoc discussions around common areas like the lunch room or a games room
  • A company policy of don't knock, don't come in could support team-wide entry into The Zone for scheduled periods of time
  • An open door would invite collaboration with other teams at other times during the day

Now, some people will obviously wonder why headphones are not mentioned as a possible solution to some of these challenges.  For some developers, headphones work well.  For others, not so much.  I personally don't want to destroy my hearing with excessive volume because I am trying to drown out the others in my area.  Plus, headphones do nothing for visual distractions.

I think there are advantages and trade-offs to every office layout but this one provides a decent balance of the two extremes.  Programmers benefit from an environment that allows them to get into The Zone to get the work done, but a collaborative environment is essential for deciding what work to do.

New Computer - Time for a major upgrade

15. December 2008 09:44 by Troy | 1 Comments

This story actually starts over a year ago when I decided that I might like to upgrade my computer.  I used to be an avid gamer... that dried up a little, but partly because my hardware was a little deficient for the latest titles.  I don't play XBox or any of the other consoles... I just never got into them.  When I do play video games, they are on the computer.  These days, it is probably more like 85% power user and 15% gamer.  I don't need the latest and greatest hardware, but it is a nice indulgence once in a while.

As I said, I started doing my research for new hardware over a year ago.  I got about half way through picking components, and got sidetracked by something else.  By the time I got back to it a couple weeks ago, I had to start all over again.

For this upgrade I would be replacing almost the entire box and its contents.  First a look at what I am replacing:

  • AMD Athlon 64 3400+ CPU @ 2.2GHz (socket 754)
  • ABIT KV8 Pro v1.1 motherboard
  • 1GB RAM Kingston Value RAM PC3200
  • 200 GB Western Digital Caviar SATA WD2000JD Hard Drive (Configured with a 12GB System partition and a 188GB Data partition)
  • DVD-RW - NEC ND-3500A
  • ATI All-In-Wonder X800XT Video Card
  • Cambridge Soundworks 4 Point Surround speakers
  • Windows XP SP2

It is a bit funny to look back now.  I first got the CPU in November 2004.  Back then, 64-bit computing was going to be all the rage, and I thought my purchase would help to future-proof my machine.  Well, here we are 4 years later, and the machine never did see a 64 bit operating system.  Only now are 64 bits becoming more adopted and stable/supported enough to make the switch.

During this round of research, I was surprised to discover that SLI (Scalable Link Interface for the semi-techs - "hooking up multiple graphics cards together so they work as one" for the non-techs) had made a comeback.  However, I was disappointed to find out that NVidia had held exclusive licensing rights which meant the only chipset that supported SLI was the NVidia nForce chipsets.  Based on what I read, these chipsets are generally of lesser quality than their Intel based competition.  So it seems that choosing a motherboard/chipset now required you to choose which video card manufacturer would get your business (ATI or NVidia), because if you wanted to support SLI (or CrossFireX) then support from the motherboard was required.

This powerplay by NVidia has finally come to an end with the X58 chipset from Intel.  This is the latest chipset that supports the latest socket 1366 Core i7 CPU's recently released from Intel.  These processors are quad core and represent the first round in some fundamental changes to CPU architecture, compared with their predacessors.

Now normally, I am an analytical, common sense kinda guy.  I don't buy brand new cars... I buy 1 year old with 30,000 KM on them.  The same goes for computer hardware, don't buy the latest, greatest model of anything otherwise you pay through the nose now, and in 6 months, the same item can be had for 1/2 the price.  I would much rather buy the 2nd generation product and save money.

<beginJustification>
This time, I couldn't get over the NVidia chipset thing.  I wanted to try NVidia video card(s) this time, because I had seen first hand some of the low quality drivers/software created by ATI over the years.  To be fair, my research indicated that ATI has gotten better in the last year or two... but I still wanted to try walking on the green grass on the other side of the fence this time.  Choosing NVidia meant wanting to support SLI (just in case I ever move to 2 cards).  Supporting SLI meant being forcefed the nForce chipset, or bite the expensive bullet and jump to the top of price mountain and go for the X58 chipset that supports both SLI and CrossFireX.  Guess what I did.
</beginJustification>

Edit: Well, about 2 or 3 weeks after buying my nVidia GTX280 based video card, they mothballed that model in favour of the GTX285.  I guess I won't be going SLI anytime soon.  I do still like the versatility of supporting both ATI and nVidia though.

Now, for a look at what I upgraded to:

  • Intel Core i7 920
  • ASUS P6T Deluxe motherboard
  • 6GB RAM G.Skill PC10666 triple channel
  • 150GB Western Digital VelociRaptor WD1500HLFS (10,000 RPM for System Drive)
  • 1TB Western Digital Caviar Black (Data Drive)
  • DVD-RW - NEC ND-3500A
  • XFX GTX280 1024MB Video Card
  • Coolermaster Stacker 830 Evolution case
  • Logitech X-540 5.1 Speakers
  • Windows Vista Business x64

So far, things are running great, and I am happy with the upgrade.
