Buzzkill
I’ve been struggling for days to put into words my reaction to the launch of Google Buzz. But the phrase I can’t get out of my head is “HOW could they screw up THIS MUCH?” Well here’s how: Google took Gmail, one of the most widely used web services on... (Continue)
Alternate dimensions
If you’re a typical designer working in the software world, the majority of products you’ll create will have strictly two dimensional interfaces — length & width only, pixels on the screen. As interfaces have evolved over the years many have gained a very simple kind of "depth": lighting effects, drop... (Continue)

The focus of the conference and my talk were how to integrate agile development with interaction design. I was very... (Continue)

Does your persona eat twinkies?

by Steve Calde on July 18, 2008

I recently stumbled across an article about personas written by Andrea Wiggins late last year in Boxes and Arrows. Wiggins does a nice job talking about how personas can help the design and development process, and some approaches for creating a good persona set. But what really gave me pause was the title: “Building a Data-Backed Persona.” Data-backed? Wait a minute…is there any other kind?

Well, yes, there are; we call them provisional personas at Cooper. These user models are based on internal assumptions and second-hand data rather than first-hand data gathered through ethnographic research techniques (most notably via in-person interviews with and observations of individual users). But in my worldview, provisional personas should always be the exception, not the rule. By definition, a “persona” implies that the archetypal user behavior patterns it describes are based on first-hand, observed behavior conducted in the field.

Wiggins’ article title was a good reminder to me that as personas have grown in popularity over the years, some fundamental principles have gotten lost in the translation. Basing design decisions on perceived user attitudes and behaviors—especially for products that target specialized roles and workflows—leads to second-guessing during the design process. Connecting the dots between research findings and persona descriptions reminds everyone about what personas are: shorthand for the key findings discovered during a real investigation.

Personas not based on real data aren’t really personas, just like Hostess twinkies aren’t really food. Sure they’ll fill you up, but in the long run those empty calories are a poor foundation to a healthy diet.

I've seen a number of teams distinguish their provisional personas by using a cartoon-like rather than photographic image to represent them. This keeps people thinking about the persona as a person, but reinforces the notion that they're a little less "real."

Chris raises a great point about presenting provisional personas in a slightly different style. If I could build upon his idea I would say it's best to aim for an "illustrative" quality. Looking "cartoon-like" or like a caricature could make personas seem less serious, which erodes their believability.
