To enable effective cross-organizational collaborations, process providers have to offer external views on their internal processes to their partners. A process view hides details of an internal process that are secret to or irrelevant for the partners. This paper describes a formal two-step approach for constructing customized process views on structured process models. First, a non-customized process view is constructed from an internal structured process model by aggregating internal activities the provider wishes to hide. Second, a customized process view is constructed by hiding and omitting activities from the non-customized view that are not requested by the process consumer. The feasibility of the approach is shown by means of a case study.

Nowadays, business supply chains for the production of complex products or services are likely to involve a number of autonomous organizations. The competitive market requires that these supply chains are highly agile, effective and efficient. Agility and effectiveness are obtained by forming highly dynamic virtual enterprises within supplier networks. We call these instant virtual enterprises (IVEs). The required efficiency of creating and operating IVEs can only be obtained by automated support for design, setup and enactment of business processes within these IVEs. This process support involves the dynamic composition of local processes of network members into global processes at the IVE level. This functionality goes significantly beyond traditional approaches for interorganizational workflow management. The approach, architecture and technology required for this dynamic network process management in IVEs are outlined in this paper. We show how the developed approach is applied in the automotive industry in the context of the CrossWork IST project.

Abstract

In many business domains, rapid changes have occurred as a consequence of digital innovation, i.e., the application of novel information technologies to achieve specific business goals. A domain where digital innovation has great potential is smart mobility, which aims at moving around large sets of people and goods in a specific geographic setting in an efficient and effective way. So far, many innovations in this domain have concentrated on relatively isolated, technology-driven developments, such as smart route planning for individual travelers. Nice as they are, they have relatively small impact on mobility on a large scale. To achieve substantial digital innovations-for example, optimizing commuting on a city-scale-it is necessary to align the efforts and related values of a spectrum of stakeholders that need to collaborate in a common business model. To this aim, the study proposes the use of service-dominant business logic, which emphasizes the interaction of value network partners as they co-create value through collaborative processes. Moving to this paradigm has significant implications on the way business is done: the business requirements for services will change faster, and the complexity of value networks required to meet these requirements will increase further. This requires new approaches to business engineering that are grounded in the premises of servicedominant logic. The paper introduces the service-dominant business model radar (SDBM/R) as an integral component of a business engineering framework. Following a design science approach, the SDBM/R has been developed in close collaboration with industry experts and evaluated through an extensive series of hands-on workshops with industry professionals from several business domains. This paper focuses on the application and evaluation in the smart mobility domain, addressing the design of new business models for digital innovation of collaborative transport of people and goods. In summary, it contributes a novel business design approach that has an academic background and relevant practical embedding.

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 can be selected on the fly during process enactment. The cooperation between the parties is specified in a dynamically made electronic contract. This contract includes a process specification that is tailored towards service brokering and cross-organizational process enactment and, hence, has to conform to market and specification standards. Process enactment, however, relies on intra-organizational process specifications that have to comply with the infrastructure available in an organization for process and data management. In this paper, we present a three-level process and data specification framework for dynamic contract-based outsourcing of complex services. We focus on services with an externally visible control flow, as opposed to simple, black-box web services. The framework relates the two process specification levels through a third, conceptual level. This approach is inspired by the well-known ANSI-SPARC model for data management. We discuss an abstract architecture for dynamic service outsourcing based on the three-level framework. We show how the framework and architecture can be placed in the context of existing infrastructures for cross-organizational process support. As service outsourcing is used more and more for core business processes requiring reliable execution, we pay special attention to transaction management.

Abstract. Reference architectures provide major guidelines for the structure of a class of information systems. Because of their fundamental role, reference architectures have to be of high quality. Before accepting a reference architecture, it has to go through a rigorous evaluation process. A number of methods exist for the evaluation of software architectures. In this paper, we analyze the main differences between concrete software architectures and reference architectures. We discuss the effects of these differences on the evaluation of reference architectures and show that existing methods cannot be directly applied for the evaluation of reference architectures. For the evaluation of a reference architecture for e-contracting systems, we used the Architecture Tradeoff Analysis Method with a number of adaptations and extensions. We present our approach and share our experiences from this evaluation process. Based on the analysis and our experiences gained, we present our vision for a method for the evaluation of reference architectures.
