To align an IT system with an organization's needs, it is necessary to understand the organization 's position within its environment as well as its internal configuration. In SEAM for enterprise architecture the organization is considered as a hierarchy of systems that span from business down to IT. The alignment process addresses the complete hierarchy.(More)
Enterprise architects seek to align enterprise processes and structure with their supporting IT systems so that enterprises can flourish in their environment. The enterprise architecture (EA) discipline has emerged from business best practices. EA frameworks are therefore mostly informal. As a result there is a lack of EA tools that can help enterprise(More)
The early requirements of an IT system should be aligned with the organization's business imperatives. To understand these imperatives it is necessary to understand the organization's position within its environment. SEAM for Business is a method designed for analyzing the competitive environment of an organization, including its relationships with its(More)
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)
Business and IT alignment demands clear traceability between the applications to be developed and the business requirements. SEAM is a systemic visual approach for modeling systems, including information systems and organizations. This paper illustrates how we represent the business role of an IT application and its platform-specific realization in SEAM. We(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)
Large enterprises need to coordinate the IT initiatives that exist in different organisational units of the enterprise. If these initiatives are not coordinated, the resulting IT system is likely to become difficult to use and expensive to develop/maintain. Enterprise architecture methods are designed for that purpose. We report on the use of a(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)
