About the Authors

René Reitsma

René Reitsma is a professor of Business Information Systems at Oregon State University’s College of Business. He grew up and was educated in the Netherlands. Prior to receiving his PhD from Radboud University in 1990, he worked at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria on a project developing an expert system for regional economic development. René joined the University of Colorado, Boulder’s Center for Advanced Decision Support in Water and Environmental Systems (CADSWES) in 1990, working on the design and development of water resources information systems. In the summer of 1998 he accepted a faculty position in Business Information Systems at Saint Francis Xavier (STFX) in Nova Scotia, Canada. He joined the faculty at Oregon State University in 2002.

René teaches courses in Information Systems Analysis, Design and Development and has ample practical experience in designing and building information systems. His motivation for writing this book was the lack of technical exercises, examples and critically discussed experiences of real-world system building in the typical Information Systems Design and Development textbooks.

Both René and Kevin are TeachEngineering.org (TE) developers. Whereas René was responsible for the design and development of the first version of TE (TE 1.0), Kevin is the designer and developer for TE 2.0 which runs on a different set of technologies and a different system architecture. Since they both are interested in making good architectural decisions, and since they both believe that much can be learned from comparing and contrasting TE 1.0 with TE 2.0, they decided to collaborate on writing this text.
