    The paper deals with business potential analysis based on the data published by Czech Statistic Authority (SÚ). It shows that the infrastructure state of the art even in small Czech companies enables to expand ERP and CRM systems, trading over Internet, Supply Chain Management and other new trends. Internet security is here of greatest importance, however it cannot be seen as major obstacle for new trading methods. The greatest challenge identified is the process and workflow optimization. To streamline workflow the document management supporting nearly seamless integration crossover the functional areas is of greatest importance. Moreover, process optimization can run into difficulties due to cross-organization functionalities of new IT architecture concepts like Service Oriented Architecture, WEB2 concepts and other methods and means. In this paper the value flow approach is shortly mentioned as an alternative to process modeling and workflow approach. Value oriented methods can overcome the process oriented approach limitations.ICT infrastructure; Business processes; Process modeling; Document management; Value chains; Business semantics

    A Constrained Object Model for Configuration Based Workflow Composition

    Full text link
    Automatic or assisted workflow composition is a field of intense research for applications to the world wide web or to business process modeling. Workflow composition is traditionally addressed in various ways, generally via theorem proving techniques. Recent research observed that building a composite workflow bears strong relationships with finite model search, and that some workflow languages can be defined as constrained object metamodels . This lead to consider the viability of applying configuration techniques to this problem, which was proven feasible. Constrained based configuration expects a constrained object model as input. The purpose of this document is to formally specify the constrained object model involved in ongoing experiments and research using the Z specification language.Comment: This is an extended version of the article published at BPM'05, Third International Conference on Business Process Management, Nancy Franc

    Modeling Workflow Processes Based on Tasks and Transactions: A Case Study of the UPM Graduate School Office

    Workflow binds, integrates the people, the processes, and the organisation into a value chain. Workflow modeling is used to redesign work processes to increase the efficiency and productivity of work. Workflow is said to be the technological cousin to Business Process Reengineering. Workflow carries the promise of integrating office work, resulting in short delay times, improved customer services and better knowledge of logistics parameters of office work. Workflow systems support business systems by maintaining the logical sequence of transitions between tasks in a work process, making sure that all related tasks or a process are completed. Tasks and transactions form an integral part of a workflow management system. However, workflow modeling is a relatively new field. Many organisations intending to conduct business process re-engineering are finding it difficult to obtain frameworks to model their workflows. This study presents the development of a framework for these organisations to model workflow processes. Old workflow processes are studied from a selected organisation and a new workflow model is designed. The performance improvements of the new workflow model over the old workflow model are then quantified. From here, a framework for workflow modeling is produced for future reference. Important concepts and issues that need attention when modeling workflows, are discussed. These issues can be used to overcome setbacks faced by many organisations while modeling their workflows, such as identifying problems in the workflow and redesigning a workflow model that will increase productivity. From this study, it is revealed that redesigning workflows require that each process be looked into carefully for its flaws and problems, to look for measures to improve the processes, and to redesign these workflow processes with attention given to issues,such as allowing the workflow model to be open, reusable, portable and scalable. With these issues in reference, workflow modeling can then be successfully implemented, for the re-engineering of any organisation

    Patterns-based Evaluation of Open Source BPM Systems: The Cases of jBPM, OpenWFE, and Enhydra Shark

    In keeping with the proliferation of free software development initiatives and the increased interest in the business process management domain, many open source workflow and business process management systems have appeared during the last few years and are now under active development. This upsurge gives rise to two important questions: what are the capabilities of these systems? and how do they compare to each other and to their closed source counterparts? i.e. in other words what is the state-of-the-art in the area?. To gain an insight into the area, we have conducted an in-depth analysis of three of the major open source workflow management systems - jBPM, OpenWFE and Enhydra Shark, the results of which are reported here. This analysis is based on the workflow patterns framework and provides a continuation of the series of evaluations performed using the same framework on closed source systems, business process modeling languages and web-service composition standards. The results from evaluations of the three open source systems are compared with each other and also with the results from evaluations of three representative closed source systems - Staffware, WebSphere MQ and Oracle BPEL PM, documented in earlier works. The overall conclusion is that open source systems are targeted more toward developers rather than business analysts. They generally provide less support for the patterns than closed source systems, particularly with respect to the resource perspective which describes the various ways in which work is distributed amongst business users and managed through to completion

    A Workflow Visual Modeler and Its Interface to Existing Workflow Management Systems

    Get PDF
    The rapid growth and complexity of today\u27s businesses have created a need for business process management approaches that will promote the efficient functioning of these organizations. Users of business process management tools greatly benefit from using visual process modeling capabilities. Cross-business interaction sets forth the need for standardization of notations in designing these models. The goal of this thesis is to study state of the art business process management notations and state of the art diagramming frameworks associated with building a Visual Modeler that can be easily integrated with existing workflow management systems. This thesis presents a Visual Modeler that has been created based on the research findings. Two case studies are presented, which show how the modeler has been effectively integrated as part of two completely different workflow management systems

    A Logic Based Modeling Approach to Managing Workflow Policy Changes

    Get PDF
    Workflow management systems are becoming increasingly important in the automation of business processes. In order to ensure proper workflow execution, workflow policies must be specified with respect to users, roles, and tasks. In today’s dynamic business environment, successful organizations must be able to respond to new customer demands and market opportunities with flexibility and speed. However, without systematic management of workflow policies, changes in organizational structure and process models can lead to inconsistent workflow specifications. Thus far, research in the change management of workflow policies has been scant. In this paper, we propose a logic-based approach to address this problem. Our contribution is three-fold: 1) a modeling language based on predicate logic is proposed, which is succinct and expressive enough to represent process model, organization model, and workflow polices; 2) workflow policy consistency in a dynamic changing environment is formally defined and analyzed based on the proposed language. 3) two algorithms are developed to check and enforce the policy consistency. To the best of our knowledge, this is the first work focuses on the formal analysis of workflow policy change management

    The trend towards e-business is increasing the complexity of intra-organizational and inter-organizational processes. To accommodate these needs, organizations must integrate their services in real time to attract and maintain customers. In the last few years, process automation and management have become a central theme in many businesses. Research areas addressing problems in this domain include: electronic commerce, business process reengineering, enterprise application integration, knowledge process management, groupware, workflow automation, electronic markets, and computer supported collaborative work. These areas have unique research approaches, but have a common interest in advancing process automation to support intra-organizational and inter-organizational work in the Internet era. Consequently, there is a great need to bring together researchers with diverse backgrounds to discuss process-related topics. The objective of this workshop is to provide a forum for researchers and practitioners interested in process automation and management to meet and exchange research ideas and results. The workshop promotes a range of research issues, though not limited to: · Business process facilitation in distributed environments · Change management in highly automated business processes · Integration of business processes in both intra- and inter-enterprises · Methodologies and tools of process automation and management · Managing business processes on the Web · Process aware system security · Process centric model driven architectures · Process flexibility, interoperability, and scalability · Process-driven knowledge delivery · Theories of conceptual, logical, and physical process modeling · Wireless process management systems · Workflow automation and management for virtual enterprises · Workflow-centric component-based software engineerin

    Authorization and access control of application data in Workflow systems

    Workflow Management Systems (WfMSs) are used to support the modeling and coordinated execution of business processes within an organization or across organizational boundaries. Although some research efforts have addressed requirements for authorization and access control for workflow systems, little attention has been paid to the requirements as they apply to application data accessed or managed by WfMSs. In this paper, we discuss key access control requirements for application data in workflow applications using examples from the healthcare domain, introduce a classification of application data used in workflow systems by analyzing their sources, and then propose a comprehensive data authorization and access control mechanism for WfMSs. This involves four aspects: role, task, process instance-based user group, and data content. For implementation, a predicate-based access control method is used. We believe that the proposed model is applicable to workflow applications and WfMSs with diverse access control requirements

    Cross organisational compatible workflows generation and execution

    With the development of internet and electronics, the demand for electronic and online commerce has increased. This has, in turn, increased the demand for business process automation. Workflow has established itself as the technology used for business process automation. Since business organisations have to work in coordination with many other business organisations in order to succeed in business, the workflows of business organisations are expected to collaborate with those of other business organisations. Collaborating organisations can only proceed in business if they have compatible workflows. Therefore, there is a need for cross organisational workflow collaboration. The dynamism and complexity of online and electronic business and high demand from the market leave the workflows prone to frequent changes. If a workflow changes, it has to be re-engineered as well as reconciled with the workflows of the collaborating organisations. To avoid the continuous re-engineering and reconciliation of workflows, and to reuse the existing units of work done, the focus has recently shifted from modeling workflows to automatic workflow generation. Workflows must proceed to runtime execution, otherwise, the effort invested in the build time workflow modeling is wasted. Therefore, workflow management and collaboration systems must support workflow enactment and runtime workflow collaboration. Although substantial research has been done in build-time workflow collaboration, automatic workflow generation, workflow enactment and runtime workflow collaboration, the integration of these highly inter-dependent aspects of workflow has not been considered in the literature. The research work presented in this thesis investigates the integration of these different aspects. The main focus of the research presented in this thesis is the creation of a framework that is able to generate multiple sets of compatible workflows for multiple collaborating organisations, from their OWLS process definitions and high level goals. The proposed framework also supports runtime enactment and runtime collaboration of the generated workflows

    The Challenges of Inter-Organizational Business Process Design - A Research Agenda

    Get PDF
    Given the increasing importance of value chain collaboration, business processes need to be more closely aligned across organizational boundaries. Hence, business process modeling and design have to be enhanced and extended to cope with inter-organizational business relationships. Among the challenges that arise are interdependencies between internal and external processes, different process logic and terminology, missing clarification of responsibilities and confidentiality issues. This paper analyzes existing approaches to business process modeling, workflow management and B2B standardization with regard to the specific requirements concerning inter-organizational business process design. It extracts the relevant concepts addressing these requirements and draws up an agenda for further research
