John Krogstie is Professor in Information Systems at NTNU, Trondheim, Norway. He is also a senior advisor at SINTEF and was employed as a manager in Accenture 1991-2000. John Krogstie is the Norwegian Representative for IFIP TC8 and vice-chair of IFIP WG 8.1 on information systems design and evaluation, where he is the initiator and leader of the task group for Mobile Information Systems. Andreas Lothe Opdahl is Professor of Information Science at the University of Bergen, Norway. His research interests include information systems and enterprise modelling, requirements determination and enterprise information architecture. He is a member of IFIP WG8.1 on information systems design and evaluation. Sjaak Brinkkemper is Professor of Organization and Information at the Institute of Information and Computing Sciences of the Utrecht University, the Netherlands. He leads a group of about twenty researchers specialized in product software enterpreneurship. The main research themes of the group are methodology of product software development, implementation and adoption, and business-economic aspects of the product software industry. He is a member of IFIP Working Group 8.1 on the "Design and Evaluation of Information Systems", of the ACM, of the Computer Society of the IEEE, and of the Netherlands Society for Informatics.
