Barbara Weber and Manfred Reichert introduced their new book on flexibility in process-aware information systems at the BPM'12 conference in Tallinn, Estonia. The book complements existing textbooks on business process management and is a must-read for anyone interested in flexible process support within information systems. The book shows that BPM is not just about making diagrams. The real challenge is to realize information systems that support business processes without jeopardizing flexibility. First reactions on the bookby the international audience were extremely positive.
