This study explores the need for user-centered design (UCD) approaches to adapt to recent societal trends of cross-sector collaborations, civil citizen involvement and e-government initiatives affecting the public sector. This is achieved by studying three cases involving such trends, taking place in the Swedish Emergency Response System. Using results from the cases, information systems development related challenges are identified and related to adaption needs for current UCD approaches. Suggestions of such adaption are provided and a number of inherent challenges for the fourth generation of UCD are discussed, including challenges concerning (a) balancing ideological versus practical needs; (b) resources; (c) lack of know-how; and (d) design techniques and tool challenges.
