Recent advances in large systems (e.g., service-oriented architecture) utilize the notion of choreography, in which there is no central control of the system. Such a task requires first developing a conceptual model to serve as a foundation for specification of choreography-based activities. The European project CHOReOS has built a UML profile for Business Process Model and Notation (BPMN) choreography-modeling capabilities. This paper is concerned with the diagrammatic tools used in the “integrated development process” as exemplified in a passenger-friendly airport model provided to highlight CHOReOS innovation. In this paper an alternative model is proposed as a conceptual base for this development methodology. The UML/BPMN description is reconstructed in terms of the proposed model to facilitate a side-by-side comparison of the two renditions of the same problem. The conclusion is that the proposed alternative approach presents a viable technique for developing a foundation that captures the relevant processes and relationships in systems. In general, the passenger-friendly airport furnishes a sample study case to show that the new diagrammatic method can be applied to high-level requirements specification in any similar development scheme.
