It may be less successful with leading-edge technologies until the technology has evolved to the point of application to a practical problem. Users have been overwhelmingly positive about the process. Software developers have also rated the technique highly, both in classroom and product development environments. It is deliberately informal, allowing people to interact with the design and with each other. The absence of high technology, abstractions, and software development jargon puts all participants on an equal footing.
People appear to have an enjoyable time with the apparatus and with each other.
The videotape provides a social record of the design process. Because the camera is out in the open, and not under control of any one participant, it also helps promote equality among all members of the group. Participation is necessary for understanding, and the developers above all must understand the design. Developer participation also helps limit the design to features that are technologically feasible, and ensures that other participants are aware of the technological possibilities. End user participants must be true end users.
