CrossFlow: Cross-Organizational Workflow Management for Service Outsourcing in Dynamic Virtual Enterprises

In this report, we present the approach to cross-organizational workflow management of the CrossFlow project. CrossFlow is a European research project aiming at the support of cross-organizational workflows in dynamic virtual enterprises. The cooperation in these virtual enterprises is based on dynamic service outsourcing specified in electronic contracts. Service enactment is performed by dynamically linking the workflow management infrastructures of the involved organizations. Extended service enactment support is provided in the form of cross-organizational transaction management and process control, advanced quality of service monitoring, and support for high-level flexibility in service enactment. CrossFlow technology is realized on top of a commercial workflow management platform and applied in two real-world scenarios in the contexts of a logistics and an insurance company

A Three-Level Process Framework for Contract-Based Dynamic Service Outsourcing

Service outsourcing is the business paradigm, in which an organization has part of its business process performed by a service provider. In dynamic markets, service providers are selected on the fly during process enactment. The cooperation between the parties is\ud specified in a dynamically made electronic contract. This contract includes a process specification that is tailored towards service matchmaking and crossorganizational process enactment and hence has to conform to specific market and specification standards. Process enactment, however, relies on intraorganizational process specifications that have to comply with the infrastructure available in an organization. In this position paper, we present a three-level process specification framework for dynamic contract-based\ud service outsourcing. This framework relates the two process specification levels through a third, conceptual level. This approached is inspired by the well-known ANSI-SPARC model for data management. We show how the framework can be placed in the context of infrastructures for cross-organizational process support

Advanced Architectures for Transactional Workflows or Advanced Transactions in Workflow Architectures

In this short paper, we outline the workflow management systems research in the Information Systems division at the University of Twente. We discuss the two main themes in this research: architecture design and advanced transaction management. Attention is paid to the coverage of these themes in the context of the completed Mercurius and WIDE projects and in the new CrossFlow project. In the latter project, contracts are introduced as a new theme to support electronic commerce aspects in workflow management

Web Services Support for Dynamic Business Process Outsourcing

Outsourcing of business processes is crucial for organizations to be effective, efficient and flexible. To meet fast-changing market conditions, dynamic outsourcing is required, in which business relationships are established and enacted on-the-fly in an adaptive, fine-grained way unrestricted by geographic distance. This requires automated means for both the establishment of outsourcing relationships and for the enactment of services performed in these relationships over electronic channels. Due to wide industry support and the underlying model of loose coupling of services, Web services increasingly become the mechanism of choice to connect organizations across organizational boundaries. This paper analyzes to which extent Web services support the dynamic process outsourcing paradigm. We discuss contract -based dynamic business process outsourcing to define requirements and then introduce the Web services framework. Based on this, we investigate the match between the two. We observe that the Web services framework requires further support for cross - organizational business processes and mechanisms for contracting, QoS management and process-based transaction support and suggest ways to fill those gaps

Supporting Collaborative Communication in a Multi-layer Meta-process Model for Evolutionary Shared Workflows

A key planning activity within a Virtual Enterprise (VE) is to establish agreed inter-organizational processes. This activity, or meta-process, has to allow for gradual evolution of the VE processes and for a multi layer development from informal business agreements to precise workflows. To support this meta-process, a collaborative electronic whiteboard supported by a tuplespace is proposed. The whiteboard supports a mixed graphical and text interface, with support for keeping track of the changes made. The participating organizations upload workflow definitions from their own IT systems into the tuplespace. Workflows are then discussed, modified and evolved before being downloaded again and mapped to the partners’ individual systems

Research on Role-Centric Collaborative Technology

With the development of e-business, the collaboration between enterprises is increasingly strengthened, which, at the same time, challenges coordination technologies in distributed enterprise transactions. Workflow management has as its priority the support of coordination functions and workflow interoperability points the way towards collaborative business environments. Though WfMC, Workflow Management Coalition, specifies the abstract interoperability, differences such as workflow concept models, ontology etc. cannot be dealt with effectively because the specification is only technical. On the other hand, portal technology focuses on the integration of information and application services customized according to roles. It can provide support for the interoperability of workflows. In this paper, workflows are integrated with portal technology. And a role centric collaborative environment is proposed which is a way out for problems existing in workflow interoperability

Introduction

This chapter provides a general introduction to this book. As such, it also describes the context of the CrossWork project that is the main source of information for this book. This project is introduced in the next chapter. We start below with discussing the business conditions for the raise of the virtual enterprise as an organization form in the modern economy. As we focus on process-oriented virtual enterprises in this book, we continue with an overview of developments in business process support technologies. Then, we introduce a framework with four aspects that can be used in a combined demand pull and technology push context – this framework is used later to structure topics discussed. In the last section of this chapter, we explain the structure of the book
