Perspectives of Information Systems by Vesa Savolainen

This book focuses on several issues in the essence of information systems and their development, as well as advanced utilization of new information technology. It includes both theoretical foundations and practical approaches for each topic and will prove useful both to scientists in the field of information system science and to practitioners in information systems development and use. Many of the topics treated here have not appeared in the literature, although they are becoming increasingly important in the development of information systems. Topics covered include: contingencies in IT decision making; intelligent executive information systems; dynamic performance evaluation of information systems; exception handling in information systems, metamethodology of information system development and mobile computing. The outstanding feature of the book is its specific mixture of subjects under one framework of thinking about information systems. A useful book to researchers and systems developers, the book can also form the basis of an advanced course in information systems development.
