In this sense, it can be said that the artifact, as it is used (and possibly studied; e.g., Howard, Boling, Rowland, & Smith, 2012) in various ways, will reveal something about the designer; and the learning that occurred in the design process—for example, that the designer had a particular perspective, used certain techniques, made certain assumptions, and so on.
As I read this, I wonder though, should the artifact not be more reflective of the client than the designer?
