Participartory Design versus Joint Application Design: Trans-Atlantic Differences in Systems Development

Abstract

JAD (Joint Application Duign) and PD (Participatory Duign) are two established user involvement methodologiu in (respectively) North America and Scandinavia. JAD is a practitionerderived methodology focusing on structured, facilitated meetings through which user involvement is elicited in systems development. PD stressu the social context of the workplace in workshops in which designers and workers collaborate in design and development activitiu. JAD and PD are introduced noting their significant ideological differences, but the focus is a comparison of the underlying techniques: participant selection, involwment points, team composition, team interaction, facilitation, structure, and development speed. Suggutions are mode for areas in which the two approaches can benefit from each other.
