Exactly what do you mean?
As an interaction designer Lynn isn’t up on the latest agile jargon. So for the first couple of days at the conference she was puzzled when she heard stories about how other agile teams had trouble identifying and working with the “customer” who defined “user stories” that the team implements. To Lynn—and most people outside the agile community—customers are people who purchase products or services. How could you co-locate “the customer” with a development team? Don’t companies have many customers? What exactly was the problem some XPers were having? Only after a Lynn realized that XP defines customer as “an informed expert who clarifies requirements for an XP team” did her confusion evaporate. An XP customer isn’t necessarily an end user or purchaser of a product. Lynn plays the role of “customer” for her XP development team when she designs features. I agree with Lynn, the definition of an XP customer is confusing.
Lesson learned: Agilists who communicate with others outside their own community need to be aware that jargon is confusing. When someone looks puzzled it may be because they don’t share your context. Bridge this gap by asking a newcomer what’s unclear. Then take the time to “decode” insider jargon for them. You'll learn something about what they do and how they think in the process.
I discussed with Lynn and Jeff Patton (another talented user-centered designer)what we each mean by “design”. To me, a software designer, design means creating a model of interacting software objects that are implemented in code. Interaction designers use a raft of techniques ranging from contextual inquiry (to understand the users' work environment), to user-centered design (to cluster tasks and identify user categories), to interaction and user interface design. All these activities to an interaction designer are “design”. It was pretty easy to understand our different views and see how they dovetailed into an overall system design process. I don’t think we should come up with an unambiguous definitios for our various activities. Besides being unrealistic, we’d all have to start speaking design Esperanto—which wouldn’t be a good thing. But I learned something. When you don’t understand what I mean, it is my problem not yours. As a good communicator I should try to bridge my ideas into your context. And when you don’t understand what I’m saying, please ask, “What do you mean by that?”
