Recently, a variety of workflow patterns was suggested for capturing different aspects in process-aware information systems (PAISs) including control and data flow, resources, process change, and exception handling. All these patterns are highly relevant for implementing PAISs and for designing process modeling languages. However, current patterns provide(More)
Organizations need more standardization and efficiency in business process execution, which is leading them to show an increasing interest in the business process management (BPM) approach. Stakeholders and workers from different departments are collaborating to obtain better products/services as a result of the BPM projects, but do not always achieve(More)
For their reuse advantages, workflow patterns are increasingly attracting the interest of both researchers and vendors. However, actual workflow modeling tools do not provide functionalities that enable users to define, query, and reuse workflow patterns properly. In this paper we gather a set of requirements for process modeling tools that aim to support(More)
Workflow activity patterns represent a set of recurrent behaviours that can be found in a wide range of business processes. In this paper we address the problem of determining the presence of these patterns in process models. This is usually done manually by the analyst, who inspects the model and interprets its elements in terms of the semantics of those(More)
Business processes executed in organization are automated through a workflow system. Currently, there are several metamodels for business process and workflow process modelling. However, the limitations of these metamodels are twofold: First, the use of organizational structure aspects is limited and second they don’t support business (sub)process patterns(More)
Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Modeling (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of(More)
Virtual Organizations (VO) have emerged as a new type of interorganizational relationship for dealing with emerging challenges. The information system support for a VO poses new challenges to system design. Recent works define three levels of abstraction, namely an intentional level, an organizational level, and an operational level. For such a staged(More)
