This paper describes, through a case study of a small software company
, an instance of the successful employment of user groups as a medium
of design. Our work indicates that effective user groups require the p
roduct development manager to accomplish a number of relatively distin
ct social processes. These include establishing trust and credibility,
managing expressions of user need, and involving users in the new pro
duct development process by enlisting them as designers. The implicati
ons of the findings are that participative models of the design proces
s make demands on the social skills of product development managers wh
ich need to be addressed in their education and subsequent career deve
lopment. Copyright (C) 1996 Elsevier Science Ltd
