Compares experimental (eg. prototyping) and analytical (eg.
specifying) approaches in systems design. Derives ′The Principle of
Limited Reduction′. Defines this as: "Relying on an analytical
mode of operation to reduce complexity introduces new sources of
uncertainty requiring experimental countermeasures; relying on an
experimental mode of operation to reduce complexity introduces new
sources of uncertainty requiring analytical countermeasures".
Concludes that a mixed approach is best, but warns that this is as yet
(1992) hypothetical.

This book is intended to mark the turn of the first century of the information age. The purpose of the book is to denote the transition from past to current to future investigations of the relationships and interactions among four major components: information systems (IS), information technology (IT), organizations, and society. These investigations share a primary focus on the interrelationships, not on the components themselves. The contributions to the book deal with the history of IS theory and technology, with the directions faced by those sharing the concerns of the field in its future research, and with attempts to draw these two views together. Five discourses collectively answer the key question: `What is the status of IS, as related to organizations and society, now that we stand at the juncture of the new century?' These discourses deal with the fundamental concepts, the classical and novel challenges, the conceptualization processes, automation, and new technology. What is our story as we turn the first century of the information age? We believe that IT is even more critical in social interaction in organizations, that human language barriers form fundamental roadblocks to IT implementation, that newer forms of IS integrate horizontally rather than vertically, and that the mix of skills and knowledge is changing. We also find that we lack integrated approaches to risk management, that new social costs are being unleashed on people by the wiring of society, and we are rushing headlong into globalized systems with our eyes closed. We reveal how the old end-user tension between central control and innovation has reappeared in the intranet world, how IT has been converted into a cultural commodity, and explore how the video screen has become the central means for discovering our relevance to our universe. We explore the surprising ways that machines have acquired human status, not through robotics, but rather through social construction. We discover new norms for defining the relationships and exchanges between human beings and computers. For example, gender defines IS success and web design defines social relationships. Consequently, we show how systems must now be developed interpretively, rather than through rational&endash;technical IS design principles used in the last century

The persona method is gaining widespread use and support. Many researchers have reported from single cases and from novel domains on how they have used the method. However, the way companies and design groups describe personas has not been the focus of attention. This paper analyses 47 descriptions from 13 companies and compares these to an analysis of recommendations from 11 templates from literature. Furthermore, 28 interviews with Danish practitioners with experience in using personas are analyzed for content on persona descriptions. The study finds that a Danish persona style has developed that is different from the recommendations in the lack of marketing and business related information and the absence of goals as differentiator for personas. Furthermore, the inspiration and knowledge on personas originates from co-workers and seminars and not much from literature. This indicates that the community of practice influences the persona style.
