This book explores the challenges regarding risks and risk management related to the growing complexity of ICT solutions. The main argument of the book is that the complexity of ICT solutions has continued to grow throughout the history of ICT, and that it now has reached a level that goes beyond our current understanding of ICT solutions and our methods of dealing with them. The contributors aim to demonstrate how the complexity of ICT solutions is increased by various integration efforts. Drawing upon theories of risk society and reflexive modernization, various case studies are used to demonstrate efforts aimed at controlling and managing the complexities of various ICT solutions. Paradoxically, these control and management measures are shown to increase, rather than decrease complexity and risk.
