Despite the large number of commercial workflow systems, object-oriented developers implement their business processes with home-made workflow solutions. Current workflow architectures are based on requirements and assumptions that don’t hold in the context of object-oriented software development. Microworkflow, a new workflow architecture, bridges the gap between the type of functionality prov...

As the workflow/BPM systems and their applications are prevailing in the wide and variety industries, we can easily predict not only that very large-scale workflow systems (VLSW) become more prevalent and much more needed in the markets, but also that the quality of workflow (QOW) and its related topics be issued in the near future. Particularly, in the QOW issues such as workflow knowledges/in...

Contemporary workflow management systems are driven by explicit process models, i.e., a completely specified workflow design is required in order to enact a given workflow process. Creating a workflow design is a complicated time-consuming process and typically, there are discrepancies between the actual workflow processes and the processes as perceived by the management. Therefore, we propose ...

Workflow systems provide automated support that enables organizations to efficiently and reliably move important data through their routine business processes. For some organizations, the information processed by their workflow systems is highly valued and in need of protection from disclosure or corruption. Current workflow systems do not help organizations to adequately protect this important...

Dynamic evolution and adaptation of workflow models due to process (re)engineering activities and dynamic changing situations of the real process is one of the most important challenges in workflow management. In this paper, we present an approach for the management of evolving workflow specifications which copes with the evolution of a workflow schema and the dynamic modification of workflow i...

Small and medium-sized enterpises need support by processaware information systems (PAIS) that offer a high degree of flexiblity in workflow execution. Current agile workflow approaches lack acceptance as they introduce a significant overhead for workflow control. Therefore, we propose a new approach for flexible PAIS, based on workflow enactment flexibility by deviation. We enable the potentia...

Workflow servers have long been heralded as the solution that can satisfy the increasing demand for a mechanism with which to track complex business processes. Although there are many commercial products available and in use, workflow servers in general still lack some key functionality. This paper describes a workflow design that addresses current research areas in workflow systems. The specif...

In this paper, we motivate integration of workflow and task modeling and present and compare workflow concept with those used in task modeling. The workflow concepts have natural task modeling correspondences and benifits of integrating them are suggested. We show how a workflow model can be utilized when modeling the tasks of a workflow participant and illustrate how endusers can benefit from ...
