Presenting the results of the ESPRIT WIDE project on advanced database support for workflow management, this book discusses combining database management and workflow management technology, especially in the areas of transaction and exception management. This technology is complemented by a high-level conceptual workflow model and associated workflow application design methodology. In WIDE, advanced base technology is applied, like a distributed computing model based on the corba standard. The usability of the WIDE approach is documented in this book by a discussion of two real-world applications from the insurance and health care domains.

This book discusses the up-and-coming blockchain technology in a structured way from the conceptual, technological, and business perspectives, thereby providing the integrated insight that is essential for truly understanding blockchain applications and their impact. While most people may know about blockchain from Bitcoin and news about its price in the financial markets, blockchain is a technology that increasingly permeates the way in which modern businesses operate. However, its dynamics and functioning remain obscure for most people. This book gives readers the tools to understand the full extent to which blockchain technology is or can be used in business. First, the book focuses on the functioning of blockchain systems, introducing basic concepts such as transactions, consensus mechanisms, and smart contracts, as well as giving a smooth introduction to the basic features of cryptography that underpin blockchain technology, e.g., digital signatures and hashing. Then, the book focuses on specific blockchain platforms (Bitcoin, Ethereum, private blockchain platforms) currently used for the implementation of cryptocurrencies and other blockchain systems. Finally, it introduces a set of tools to understand and analyze the suitability of blockchain technology in different business scenarios from the business model, and business operation perspectives. Examples and case studies of blockchain applications currently in production are discussed extensively across the book. This book targets students and educators with an interest in blockchain technology providing a one-stop shop to obtain a deep and complete insight in blockchain technology and its applicability in different business scenarios. The textbook is designed primarily for third and fourth year undergraduate students in industrial engineering, business and management, and information systems. However, it can be adopted also in the computer science majors, since it does not strictly require any specific pre-requisite knowledge. At the graduate level, this book can be used in courses for industrial engineering, information systems, and management students. Finally, the book is also of interest to practitioners, like business analysts, process analysts, and information system architects, to understand the enabling and transformative potential of blockchain in a given business scenario.

In Beyond E-Business: Towards Networked Structures Paul Grefen returns with his tried and tested BOAT framework for e-business, now fully expanded and updated with the very latest overview of digitally connected business; from business models, organization structures and architecture, to information technology. What used to be termed "e-business" is now simply business as usual. Today’s successful organizations are complex; they are part of dynamic business networks built on digital channels, going far beyond traditional e-business. This text provides invaluable insights of modern e-business integrated with networked business, going much further than the usual analysis of traditional e-business texts. Included is coverage of the Big Five—social media, mobile computing, big data, cloud computing, and the internet of things --as well as service-oriented business and technology. This essential text provides a compact roadmap to networked e-business for engineering, information systems or business students as well as professionals in the field.

Dynamic Business Process Formation fuses practical needs with theoretical input to present important research innovations in supporting Instant Virtual Enterprises (IVEs). This new organization type brings a combination of business dynamism and explicit business process structure to domains where on-the-fly formation of well-organized business networks is required to deal with the complexity of new products or services under high time pressure.This book contains the main results of the IST CrossWork project, and, importantly, looks beyond the boundaries of this project and sources input from related projects and general trends in collaborative enterprises and the automotive industry. Both the business and technical aspects of Virtual Enterprise coordination are covered within the modular structure of the book, which enables readers from different backgrounds to benefit from the book according to their interests.

Many organizations are currently undertaking a digital transformation to improve their business processes and better achieve their goals. This Handbook provides a comprehensive overview of contemporary trends and research at the point where business process management and digital transformation meet. Presenting a multidisciplinary approach, it demonstrates the close link between these two fields through engagement with theory and practice.Bringing together a diverse set of carefully selected experts, the Handbook features both business and technical perspectives, covering important issues including the models for process design, structures and systems for process execution, process monitoring and analysis, and advanced application domains, highlighting the smart industry and healthcare application domains. Key concerns, techniques, and methods for the design and specification of business processes in the context of digital transformation are explored alongside the structures, architectures, and systems for the implementation of these processes. Ultimately, this Handbook provides the reader with a solid understanding of the state-of-the-art in these two domains.The Handbook on Business Process Management and Digital Transformation is an essential resource for scholars and students of business management, industrial engineering, information systems, management and sustainability, organizational innovation and behaviour, and technology and ICT. Business professionals and digital technology managers looking to better understand the overall importance of process-oriented digital transformation will equally find this to be a fundamental reference work.
