    A Framework for XML-Based Workflow Interoperability - The AFRICA Project

    With the advance of electronic business relationships over the internet, the linking of cross-organizational business processes in virtual supply chains and other scenarios is rapidly increasing. Existing standards for the interoperability of information systems on the business process level are being adapted to suit the needs of the Internet economy. Especially the use of XML as a domain-independent encoding standard for business documents has led to the development of business frameworks such as BizTalk or open/EDI, and interoperability mechanisms that support these standards are being developed. In this paper we describe an architecture for the support of cross-organizational workflows through XML messages. This architecture has been implemented and tested within the AFRICA project at the University of Muenster, Germany. While our work is based upon the emerging Wf-XML standard of the Workflow Management Coalition, it contains a number of significant enhancements that provide a secure, reliable management of global workflow processes

    Information sharing across multiple humanitarian organizations—a web-based information exchange platform for project reporting

    This article analyzes information sharing problems in the humanitarian development sector and proposes the concept of a web-based exchange platform to face some of the technical challenges. The "Development Information Exchange System” is a mediator-wrapper-architecture that uses XML documents to loosely couple autonomous and heterogeneous information systems. Detailed project information of humanitarian organizations that resides on data provider systems can be formatted with XSL stylesheets according to the needs of the users and shared within or between organizations. The system can help to close the control loop by providing qualitative information about humanitarian projects. This makes project management more efficient. The proposed architecture solves an interface problem between the various partners and stakeholders of humanitarian projects. It is a first step towards a service-oriented architecture between humanitarian organizations. The next step could be the definition of cross-organizational business processes. These processes may be defined platform-independently with the Business Process Execution Language for Web Services. A prototype of the exchange platform is presented and evaluated in this articl

    Resilience Analysis of Service Oriented Collaboration Process Management systems

    Collaborative business process management allows for the automated coordination of processes involving human and computer actors. In modern economies it is increasingly needed for this coordination to be not only within organizations but also to cross organizational boundaries. The dependence on the performance of other organizations should however be limited, and the control over the own processes is required from a competitiveness perspective. The main objective of this work is to propose an evaluation model for measuring a resilience of a Service Oriented Architecture (SOA) collaborative process management system. In this paper, we have proposed resilience analysis perspectives of SOA collaborative process systems, i.e. overall system perspective, individual process model perspective, individual process instance perspective, service perspective, and resource perspective. A collaborative incident and maintenance notification process system is reviewed for illustrating our resilience analysis. This research contributes to extend SOA collaborative business process management systems with resilience support, not only looking at quantification and identification of resilience factors, but also considering ways of improving the resilience of SOA collaborative process systems through measures at design and run-time

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

    Get PDF
    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

    Developing an inter-enterprise alignment maturity model: research challenges and solutions

    Get PDF
    Business-IT alignment is pervasive today, as organizations strive to achieve competitive advantage. Like in other areas, e.g., software development, maintenance and IT services, there are maturity models to assess such alignment. Those models, however, do not specifically address the aspects needed for achieving alignment between business and IT in inter-enterprise settings. In this paper, we present the challenges we face in the development of an inter-enterprise alignment maturity model, as well as the current solutions to counter these problems

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

    Get PDF
    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
