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)
Recent discussions raised by the BPM community illustrate the increasing demand of practitioners in the solutions for descriptive, knowledge-intensive processes. As a matter of fact, a majority of modeling formalisms presented on the market today fails in providing an appropriate level of adaptability while ensuring validation and control for such(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)
SEAM is an enterprise architecture method that defines a visual language for modeling. Our goal is to provide formal semantics for SEAM. Model simulation, model comparison, and refinement verification are practical benefits we expect from this formalization. This paper complements the existing SEAM semantics by formalizing property-property relations. This(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)
Process-aware information systems (PAIS) supporting knowledge-intensive processes are gaining importance nowadays. Crisis management process is an example of a knowledge-intensive process that is grounded on vast experience of multiple actors (e.g., city services, volunteers, administration) and their collaboration. Automated crisis management systems have(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)
