More 2003 IA Summit - Trip Reports
Stacy Surla shares her thoughts on the IA Summit. Comment to ssurla@aspensys.com.

Keynote Presentation
Stewart Brand

It was both baffling and obvious. Stewart Brand at the 2003 Information Architecture Summit? Well, why not? People interested in IA also tend to be fascinated by other wacky topics, like semiotics, applied anthropology, and building design and construction.

I don't expect to see any contributing editors from Fine Homebuilding Magazine at an IA conference, but when I heard Brand was going to be the keynote speaker this year I was able to say (once again) "Yes! I am in the right profession!"

Stewart Brand is famous for many things, including the Whole Earth Catalog and the Long Now Foundation (with some spectacular ventures, including the creation of the 10,000 Year Clock, and the Rosetta Project's compilation of the world's largest collection of linguistic data).

But most people know Brand as the author of How Buildings Learn. This book is an empirical look at buildings as they change over time. It is also an insightful exploration into the kinds of things that create robust and adaptive systems (or obsolete and useless ones). It looks at these issues in a way that helps readers develop deep insights of their own into how all kinds of things might work. Java programmers, for instance, think the book is all about coding. Personally, I liked it for helping me understand my primal reactions to small vernacular houses. And for making me think about how orders of change might fit into the design of complex information systems like websites.

The Main Points

I took away two main things from Brand's keynote presentation at the Summit. The first is the concept of pace layering, a notion that is helping me think about how stuctures can be built so they can continue to be useful over time. I'll explore this concept a very little bit below, particularly as it might pertain to websites. I don't know yet how it does, but I'm to start a discussion about it within DCIA.

My other takeaway is introspection about what I ought to be doing with my life. Am I focused on the big picture, on the key areas, on the projects that matter? Stewart Brand is a person who is certainly doing with his life what he should be doing. This spirit of not settling for less than the real thing is appropriate to IA's current state of development, in my opinion. I will continue my own introspection in private, but will record here Brand's advice to IAs regarding balancing work and making a contribution. He paraphrased Freeman Dyson, who told young scientists that early in their careers they should focus on what's hot, what's current, what's fashionable (the top layer of pace layering as described by Brand). Make a name for yourself, get your career working. Then later on, after you're established, you can be more thoughtful, concentrate on an area that's not fashionable, and work on the deep structures. And make a difference there -- or not, it won't hurt your career then!

Pace Layering

Here are a few key concepts, or perhaps the same concept stated different ways:

  • Systems contain layers that degrade or change at different paces.
  • Built structures that can adapt are the ones that continue to stick around.
  • Systems whose slow, medium, and fast-changing layers are balanced will be robust and adaptive, and will continue to be useful for a long time.
Pace layering is easy to see with with architecture. A building has 7 or 8 layers that degrade or change at different paces. These include the frame, foundation, exterior skin, systems, finishes, and furnishings. High-maintenance finishes (wooden gingerboard, white shag carpet) and inaccessible systems (radiant heating in concrete) will make structures ultimately unmanageable and obsolete. Therefore, the notion: "to get buildings to last a long time, design them to adapt" can result in a practical to-do list for designing and building a building. We can also use the concept to say something useful about civilizations, as shown below.

But what does "designed to adapt" mean for websites? Websites can be described in terms of layers that change at different paces. But does this notion give us a to-do list for information architecture?

Below is my first cut at a pace layering diagram for websites. According to Brand, if the pace layering model is a good one, then it should be fractal. So I've broken out more detail for some areas that may have their own internal paces.

What's Next

Frankly, I don't know yet what this model can do for us. I do think a good conversation on the topic will be fruitful. Besides arguing about the layers themselves (e.g. servers aren't really equivalent to structural foundations, so maybe they're actually the fastest layer), focusing on the IA layers should reveal some interesting ideas.

James Melzer discusses the keynote and Brand's famous book on his blog (scroll down a screen or two). He, too, finds pace layering interesting for IA.

Tanya Rabourn has posted her notes on the session. Brand's conceptual system helps her focus on elements that change at different rates depending on functionality; and she recognizes the importance of isolating frequently-changing elements from more constant ones in an information design.

Adam Green has another early set of musings on the topic. One caveat he offers is that, unlike software, websites do not tend to grow organically, but rather get scrapped every few years. Further, even site fixes often involve demolishing large portions of the structure and organizing the content objects in new relationships to one another -- which would, if we're trying to maintain a parallel, be like disappearing the building and keeping only the furniture.

Yes, but not really. There's more to ponder here.
