"The book is written by two renowned BPM experts and a must-read for anyone interested in flexible process support within information systems. It shows that BPM is not just about making diagrams. The real challenge is to realize information systems that support processes without jeopardizing flexibility. The authors present a wide range of powerful techniques to support this." Wil van der Aalst, Eindhoven University of Technology, The Netherlands "Comprehensive coverage of flexibility in PAIS, clear explanation of concepts and their practical applications, and easily understandable examples - this book is an excellent choice for students, computer scientists, and practitioners." Stefanie Rinderle-Ma, University of Vienna, Austria "If there would be any doubt left, this book annihilates the picture of workflow systems as being rigid, unyielding types of information systems. The authors draw from their deep knowledge of the field to explain the state-of-the-art with respect to flexibility mechanisms: A rich and highly readable treatise." Hajo Reijers, Eindhoven University of Technology, The Netherlands "The book provides an excellent description of recent advancements in the area of business process flexibility.
