Many companies expect their IT developers to understand their business strategy and to specify IT systems that will impact favorably the execution of their business strategy. Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) address these issues. In this paper, we present a course that introduces EA and SOA to undergraduate CS students.(More)
Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these models, two hierarchies exist: an organizational level hierarchy (describing systems' construction)(More)
Business process modeling techniques, such as BPMN, encourage the early specification of the exact order in which the activities of the process will be executed. However, a business process may be exposed to different environments and subjected to many conditions in which a sequence cannot be identified at design time. We present declarative business(More)
Future developments for enterprise process management must evolve from the current systems based on rigid, workflow based processes into context-aware, agile dynamic structures, which exploit local adaptability. In this idea paper, we define two forms of process agility. To enable these forms of agility, we present our vision of context-aware business(More)
IT organizations that wish to implement the best practices recommended by the IT Infrastructure Library (ITIL) need to specify the level of service provided to their customers. The implemented service needs to comply with this specification. We propose a method for describing declarative specifications of services, and of their planned constructions. These(More)
