    From Business to Process Models: a Chaining Methodology2006In: Proceedings of the 18th International Conference on Advanced Information Systems and Engineering (CAiSE’06), 2006Conference paper (Other academic)
    Abstract [en]

    In this paper we discuss the problem of how to go from a business model to a process model in a systematic way. Business models are economic models used for business analysis, while process models capture low-level business activities and their coordination. We propose a method that starts with a business model where the main actors and their relationships are identified. This forms a basis for design of a final process model. Processes are described in terms of patterns stored in a pattern library.

    A Value-Based Foundation for Service Modelling2006In: ECOWS '06 Proceedings of the European Conference on Web Services, 2006, p. 129-137Conference paper (Other academic)
    Abstract [en]

    A broader use of e-services for cross enterprise collaboration requires the services to be analysed and designed with a clear business focus. From a business perspective, the e-services must support the primary values that an organization strives for. From an operational perspective, the e-services must be devised such that they support the day-to-day activities in the business. In this paper, we report on an effort to use value models and "service process models" as the foundation for analysis and design of e-services. Value models facilitate the exploration of new e-services, whereas service process models relate e-services to specific activities in an organization's business processes. We elicited a set of principles and models for analysis and design of e-services, and we discussed the experiences of practicing the principles in a project from the health sector. Having a well-defined alignment of software and business values provides benefits for service requirement gathering, service identification and service validation.

    Service collaboration environment2006In: Proceedings of the International Workshop on E-Services in Public Administration, 2006Conference paper (Other academic)
    Abstract [en]

    The extended use of services for cross enterprise collaboration rely on that the use and provisioning of services are simple, and yet that the provided services follows a coherent set of rules for their behaviour and interaction. This balance between simplicity and regulation is crucial for the stepwise evolution of both business and software services. In this paper we present the concept of a service collaboration environment to denote a domain of services working under a limited set of regulations. We use the theory of competitive market forces to define a set of guidelines that aims to enable service growth by stimulating new service consumers and providers to enter the environment. Furthermore, the guidelines, being both technical and business oriented, can be applied to balance the competitive forces from service consumers and providers.

    Approaches to Service Interface Design2005In: INTEROP-ESA International Conference Proceedings of the INTEROP: Workshop “Web services and Interoperability”, 2005Conference paper (Other academic)
    Abstract [en]

    Services can be seen as an extension of the component and object oriented paradigms. Just like objects and components services need well defined, well documented interfaces. However, unlike most components and objects, services must be designed to work in a wide range of computing environments. Service design must cope with problems ranging from the integration of remote-procedure based legacy systems to the use state-of-art message based orchestration servers. In this paper we provide an overview of three fundamental approaches to service interface design; method centric, constrained and message centric interface design. Furthermore, we briefly discuss how each approach impact the use of web service standards and conclude with future research directions.

    Supporting Development and Evolution of Service-Based Processes2005In: The IEEE Proceedings of the International Conference on e-Business Engineering, Washington, DC, USA: IEEE Computer Society , 2005, p. 647-655Conference paper (Other academic)
    Abstract [en]

    When designing executable enterprise processes, the alignment between business and technical requirements is still one of the central problems. Process specifications obtained from the pure business perspective commonly cannot be executed "as-is" due to constraints of information systems given in the form of existing software services. In this paper we introduce several concepts targeted towards aligning business processes and service-based systems. The notion of realization levels is introduced to discern the level of business conformance. Furthermore, a model of system constraints is introduced to guide the developer to process realizations with high business conformance. By the combined use of the concepts, structured development and evolution of process realizations is enabled by continuous tracking of the alignment between business and the supporting technology.

    Using Multi Tier Contract Ontology to DeduceContract Workflow Models for Enterprise Process Interoperability2005In: Proceedings of the INTEROP EMOI Workshop. CAiSE’05 Workshop, 2005Conference paper (Other academic)
    Abstract [en]

    Ontologies are being proposed as a medium for affecting enterprise application integration. Though it is widely accepted that ontologies can support inter- enterprise interoperability, the exact nature and extent to which ontology may be useful is uncertain. We promote the use of ontology in a two-fold way: first, as a knowledge base for fostering human-to-human shared understanding; second, as an ‘interlingua’ for promoting human-to-machine specification as well as semantics-to-execution. The proposed concept is described using a case scenario in the realm of legal business contracts, followed by their integration to the business domain, with an objective to model contract compliant business process models. With the case, we illustrate the use of Multi-Tier Contract Ontology (MTCO) to deduce a high level, partial business process model named the Contract Workflow Model (CWM). Such a model, from the business process perspective, may be used as a skeleton for designing internal business processes for each individual contracting party, or for mapping to existing processes.

    Concepts of Flexibility for Efficient Integration of B2B Processes2004In: Proceedings of the International Workshop on Modelling Inter-Organizational Systems (MIOS’04) / [ed] Meersman, R, 2004, p. 431-443Conference paper (Refereed)
    Abstract [en]

    Business-to-Business (B2B) e-commerce is emerging as trading parties are attempting to integrate electronically, to automate exchange of their services. To be able to collaborate, enterprise processes must expose compatible public behavior. It is a common need for a company to collaborate a business with many partners. A problem is that, even agreeing on information to be exchanged, the partners usually expose different requirements for protocol and logic of interactions. Therefore, it becomes necessary for companies to redesign process models to accommodate to a new partner. As the result, the company must engage considerable resources for designing and verifying new process specifications, as well as for maintaining them. In this paper, we propose a framework for flexible modeling of enterprise processes, to support a larger scale of B2B integrations. The proposal is based on a set of concepts of flexibility that enable partial process specifications, depicting thus a wider scope of business scenarios that a company is willing to conform in a B2B context. The complete process specification is made after B2B parties agree on a strict public protocol and enforced by runtime transformations. The proposed framework for flexible process modeling is aimed to speed up integration of partner processes as it increases ability for process matching without requiring changes in their design.

    Process Integration for the Extended Enterprise2006Doctoral thesis, monograph (Other scientific)
    Abstract [en]

    In many industries today, the speed and costs with which new products are delivered to customers provide the basis for competitive advantage. Electronic business (e-business) is a concept that shortens the “time to market” and enables transacting at lower costs. Currently, one of the main limitations in the exploitation of e-business is the lack of efficient Information System (IS) integration, both in intra- and cross-enterprise environments. Intra-enterprise integration is complex, as the business needs and the underlying information systems do not evolve in accordance. In the cross-enterprise context, transparent system integration is hardly achievable due to the incompatibility of the services of the involved partners. This means that the future success of the integration depends heavily on the possibilities offered in terms of interoperability among the involved enterprises. The Business Process Management (BPM) discipline addresses this challenge, as processes have been recognized as key mechanisms through which most intra- and cross-enterprise interactions take place. The development of methods for successful integration of process models is one of the essential issues for the use of the BPM approach in the application and evolution of e-business.

    In this thesis, we address two topics in the area of business process management: 1) intra-enterprise process integration which concerns alignment between the internal business processes and information systems enclosed in the form of software services and 2) cross-enterprise integration which concerns coordination of the internal business processes of an enterprise with the processes of its suppliers, intermediaries, or customers. The goal of the thesis is to add theoretical and applicable knowledge to the field of business process management by using the proposed approaches for improvement of process integration in intra- and cross-enterprise contexts.

    Flexible Realisations of Business Processes Using Existing Services2006In: Proceedings of the 8th International Conference on Enterprise Information Systems (ICEIS 06), 2006, p. 165-172Conference paper (Other academic)
    Abstract [en]

    When realizing executable business process models, in most situations process specifications collide with specific properties of existing services. In this paper we propose an approach for relaxation of the business process specification to enable flexible integration between the process and existing services. The approach is based on the notion of visibility, which allows a categorized relaxation of the process specification by not requiring every process state to be distinguished after the process is realised with existing services. The categories of visibility presented in this paper are applied by indicating flexible elements in the process design phase. The presented approach stimulates the alignment between business processes and existing services, facilitating a larger scale of transparent process realisations.

    Flexible Integration of Business and Technology Using Service-Based Processes2005In: The Proceedings of the 6th BPMDS Workshop. CAiSE’05 Workshops, 2005Conference paper (Other academic)
    Abstract [en]

    When designing executable enterprise processes the assumption of a transparent integration with existing systems is unrealistic. These systems, represented by software services, may impose various constraints. Using a process description framework, in this paper we examine how the design of executable business processes is affected by technical issues. Furthermore, we examine rules to which system designers should adhere to when designing services, to enable a larger scope of “as-is” realizations of business processes.

    Abstract [en]

    In most organizations, business process realizations must be aligned with existing systems, which can impose specific requirements. Currently, however, there is no way to track the alignment between business processes and corresponding technical implementations. The authors' proposed framework offers a systematic way to classify and assess technical realizations of business processes.

    Enabling Business Process Interoperability Using Contract Workflow Models2005In: The Proceedings of the 13th International Conference on Cooperative Information Systems (CooPIS’05), 2005, p. 77-93Conference paper (Other academic)
    Abstract [en]

    Business transactions are governed by legally established contracts. Contractual obligations are to be fulfilled by executing business processes of the involved parties. To enable this, contract terms and conditions need to be semantically mapped to process concepts and then analyzed for compliance with existing process models. To solve the problem, we propose a methodology that, using a layered contract ontology, deduces contract requirements into a high-level process description named Contract Workflow Model (CWM). By applying a set of transformation rules, the CWM is then compared for compliance with existing, executable process models. By the use of its concepts, the methodology enables comprehensive identification and evolution of requirements for interoperability of processes of the contracting parties.

    Modeling Image Processing Tasks As Flexible Workflows for Improved Quality of Service2004In: The IADIS Applied Computing / [ed] Nuno Guimarães and Pedro Isaías, 2004, p. 363-370Conference paper (Other academic)
    Abstract [en]

    Processing of nontrivial images is a difficult task performed throughout a set of ordered steps. Besides the basic functionality that a process must satisfy, quality of service goals are to be met. Images should be processed within a certain time and a certain quality should be attained. To manage image-processing tasks in the optimal way, the process goals must be defined explicitly and their fulfillment has be controlled. Modeling image-processing tasks with workflows would enable control of the fulfillment of goals. In addition, by introducing flexible semantics in the workflow, the process could be executed along optimal execution alternatives. In this paper, we propose an approach to model the class of image processing tasks with workflows that would, based on the extended semantics, allow for flexibility in the process execution toward optimal goals fulfillment.
