    Business Process Modeling: Classification and Perspective
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Yan, Zhixian; Mazzara, Manuel; Cimpian, Emilia; Urbanec, Alexander
    In the last decades many different approaches and tools have been developed for business process modeling. In this paper we discuss the conceptual issues in process modeling, and present various considerable modeling approaches in the context of BPM and SOC, including both semantic and non-semantic methods and referring to industrial standards and theoretical foundations. Furthermore, we provide an outlook to essential future study on process modeling, especially where semantic process modeling can play an important role in the real world business process applications.

    Flexibility Enhancements in BPM by applying Executable Product Models and Intelligent Agents
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Kress, Markus; Seese, Detlef
    In this paper we present an alternative approach to model and execute business processes. The approach combines a compact model with an intelligent control flow mechanism. Instead of using a pre-designed process model that is executed dur- ing runtime by a workflow engine, we use a special model called executable product model (EPM) that is executed by a multi-agent system. The EPM provides a compact representation of the set of possible execution paths of a business process by defining information dependencies instead of the order of activities. In our approach the ap- plication of intelligent agents takes advantage of the flexibility provided by the EPM. Relational reinforcement learning (RRL) with a genetic algorithm (GA) is applied for managing the control flow. In experiments we show that business processes can be executed successfully with our approach and that the application of machine learning leads to significant performance gains.

    Towards Autonomic Processes and Services
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Dustdar, Schahram
    More than ever, computing devices are becoming more powerful and networked, organizational boundaries are dissolving, and underlying information systems become more complex, thus requiring higher degrees of autonomic behavior of the business processes and software services they support. In this keynote talk the main challenges towards building the required novel conceptual abstractions as well as needed technological implementations are presented and discussed.

    Pricing (Composed) Web Services
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Günther, Oliver
    In this invited talk we discuss the challenges associated with composing and pricing web services. We present the results of an online experiment, where subjects were confronted with a variety of choices and decisions relating to web service markets and service composition. Our analysis shows that people expect the price of a composite web service to be lower than the sum of the prices of the elementary services, i.e., users are not willing to pay for aggregation by a third party. To obtain a viable business model for composite web services, non-standard pricing mechanisms, such as auctions and negotiations, possibly supported by electronic agents, have to be taken into consideration. Usage-based pricing schemes, combined with an option to switch to a flat subscription, seem most appropriate to penetrate the developing market for web services. – This is joint work with Frank Leymann and Gerrit Tamm. A full version of this paper will be published shortly in the International Journal of Business Process Integration and Management.

    Towards Dynamic Integration: Deployment of UDDI Registries in a Service-Oriented Architecture
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Nowicki, Adam; Niesler, Andrzej
    The important premise of adopting service-oriented architecture (SOA) is the ability to increase enterprise agility through composition and reuse of coarse-grained services. However, without dynamic integration and alignment with business processes SOA would be nothing but yet another abstract architecture proposal. The response to that issue is Universal Description, Discovery and Integration (UDDI) protocol and deployment of UDDI registries. Several years of building universal and publicly available business registry showed, that the global monolithic approach is not what the market is expecting. This paper discusses the problem of dynamic integration in an SOA-enabled enterprise and provides insight on the reasons why the decentralised approach and private registries should be considered as an alternative solution. A proposal of the enhanced Web services registry model has been presented.

    Business-Driven Service Modeling - A Methodological Approach from the Finance Industry
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Kohlmann; Falk; Alt, Rainer
    Service-orientation is recognized as an important enabler for increasing the efficiency of transformation processes in business. Improved flexibility is becoming a necessity in many competitive industries when companies are forced to quickly meet dynamic customer needs and when organization concepts are increasingly based on networking with partners. A key requirement for the flexible bundling of individual tasks in business processes are service models that have a clear link to how business is conducted and that are shared within a specific community. However, there is a lack of methodologies for combining technical and business-driven service modeling and aligning it with (business) process management as well as sourcing strategies. For this purpose, this research discusses techniques for service modeling and presents an extended service modeling concept for the business-driven discovery of services. The banking industry which currently is facing profound transformation challenges was chosen to motivate and demonstrate the applicability of the suggested model.

    A Native Approach to Service Oriented Modeling and Implementing of Business Processes
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Gruber, Jacek; Brzozowski, Tomasz
    For the last few years Sybase Company [SYB] proved its commitment to improving business modeling by creating integrated infrastructure for modeling enterprise businesses. Thanks to the incorporation of Service Oriented Architecture (SOA), Web services and business process execution languages, Sybase has significantly extended business modeling in almost every direction. This article is intended to provide a short survey of Sybase approach, examining its usage and related key aspects - among them: defining static and dynamic view of business organization, implementing business processes by specifying external services and deploying processes to a target execution platform, which allows orchestration and execution simulation.

    Designing User Interfaces for Mobile Business Processes using Messaging Application
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Pajunen, Lasse; Chande, Suresh; Galal, Sameh
    Mobile devices have user interfaces which enable users to interact with each other in an intuitive manner. The most popular applications are voice calls and messaging. In contrast, business communication requires support for long- running interactions between people and automated systems. This makes the use of mobile device for business communication complicated with the existing user interface capabilities. Especially, in cases of mobile device centric processes, intuitive and effective mobile user interface is needed. A mobile business process is sub class of general business processes where user interaction is performed using mobile devices. In this paper, we will describe our experiences in enhancing the existing messaging platform and providing an intuitive way for users to access and interact with business processes. We will describe our approach and a proof-of-concept system with convenient and natural user interface that compares to the other common functionalities of the mobile device. The system consists of four parts: seamlessly integrated way to start new mobile business process instances, ways to check status of existing process instance execution, ways for notifying user on external events within a process, and ways on how users can react on these external events.

    Supporting Differentiated Services With Configurable Business Processes
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Tao Tao, Aries; Yang, Jian
    In order to support business service flexible and reusable, it is desirable to provide users or applications the same service but with different service quality, dif- ferent interaction paths, or different outcomes. We call this design principle as Service Differentiation. In this paper we present a fully working service design method where variability is externalized as business policies so that the business process(es) does not need to be altered for any anticipated changes. Service differentiation is realized by configured business processes and interfaces, and the dynamic ’binding’ between user/application with a specific interface is determined by policy during service invocation time.

    Towards an Agile Service System for a Global Call Center
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Cheng, Isaac; Krishna, Vikas; Boyette, Neil; Bethea, Joel
    In this paper, we share our experience with applying service-oriented techniques to improve the agility of a real-world global service system. We improved the process independence of the service system by decoupling application development from process management using a framework that is based on models and rules. We analyzed various aspects of the system and the impact of technologies being deployed. Our experience is documented as a case study as we anticipate that similar techniques can be applied to improve the agility of other significant service systems in the future.
