Organizational Semiotics occupies an important niche in the research community of human communication and information systems. It opens up new ways of understanding the functioning of information and information resources in organised behaviour. In recent years, a numberof workshops and conferences have provided researchers and practitioners opportunities to discuss their theories, methods and practices and to assess the benefits and potential of this approach. Literature in this field is much in demand but still difficult to find, so we are pleased to offer a third volume in the miniseries of Studies in Organizational Semiotics. This book is based on the papers and discussions of the fifth workshop on Organizational Semiotics held in Delft, June 13-15, 2002, hosted by Groningen University and Delft Technical University in the Netherlands. The topic of this workshop was the dynamics and change in organizations. The chapters in this book reflect recent developments in theory and applications and demonstrate the significance of Organizational Semiotics to information systems, human communication and coordination, organizational analysis and modelling.In particular, it provides a framework that accommodates both the technical and social aspects of information systems. The mini-series presents the frontier of the research in this area and shows how the theory and techniques enhance the quality of work on information systems.
