In this paper we examine the suitability of the Business Process Modelling Notation (BPMN) for business process modelling, using the Workflow Patterns as an evaluation framework. The Workflow Patterns are a collection of patterns developed for assessing control-flow, data and resource capabilities in the area of Process Aware Information Systems (PAISs). In(More)
Web services composition is an emerging paradigm for application integration within and across organizational boundaries. A landscape of languages and techniques for web services composition has emerged and is continuously being enriched with new proposals from different vendors and coalitions. However, little effort has been dedicated to systematically(More)
UML is posited as the “swiss army knife” for systems modelling and design activities. It embodies a number of modelling formalisms that have broad applicability in capturing both the static and dynamic aspects of software systems. One area of UML that has received particular attention is that of Activity Diagrams (ADs), which provide a high-level means of(More)
Web services composition is an emerging paradigm for enabling application integration within and across organizational boundaries. A landscape of languages and techniques for web services composition has emerged and is continuously being enriched with new proposals from different vendors and coalitions.

In this paper an evaluation of BPMN is presented, using the Workflow Patterns as an analysis framework. The analysis provided for BPMN is part of a larger effort aiming at an unbiased and vendor-independent survey of the expressive power of some mainstream modelling languages for process-aware information systems. It is a sequel to an analysis series where(More)

The Unified Modelling Language (UML) is a well-known family of notations for software modelling. Recently, a new version of UML has been released. In this paper we examine the Activity Diagrams notation of this latest version of UML in terms of a collection of patterns developed for assessing control flow and data flow capabilities of languages used in the(More)
The Business Process Execution Language for Web Services (BPEL) has emerged as a standard for specifying and executing processes. It is supported by vendors such as IBM and Microsoft and positioned as the “process language of the Internet”. This paper provides a critical analysis of BPEL based on the so-called workflow patterns. It also discusses the need(More)
As a result of the growing adoption of Business Process Management (BPM) technology, different stakeholders need to understand and agree upon the process models that are used to configure BPM systems. However, BPM users have problems dealing with the complexity of such models. Therefore, the challenge is to improve the comprehension of process models. While(More)
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(More)
