September 15, 2004: In Extending a Technique: Group Personas, Mike presents a detailed walkthrough of the development of personas for group behavior (his example is a family at an amusement park). It's a nice gloss on persona development, and worth reading whether you're working with groups or individuals. In general, I'm a strong believer in persona/scenario development as a "way in" to designing an interface. I don't put quite as much stock in personas as some people; I think they are extremely important for defining problems, but they just feel a bit unwieldy as an ongoing part of the design process - that whole "What would Glenda do?" thing. Anyhow, go read the article :)
