The objective of this thesis is to investigate how BPM lifecycle practices can be aligned with the abstraction layers of Model-Driven Architecture—namely the Computation Independent Model (CIM), Platform Independent Model (PIM), and Platform Specific Model (PSM)—to support consistent and efficient business process digitalization. Following a Design Science Research approach, the study develops a conceptual transformation model that enables the systematic transition frombusiness-oriented process representations to technically implementable system architectures.

The research is grounded in a qualitative case study of the customer event process at Raiffeisenbank Oberfreiamt. At the CIM level, the process is modelled using BPMN to capture business logic, roles, and responsibilities independently of technical considerations. At the PIM level, business activities are abstracted into stable functional responsibilities and platform-independent application services. At the PSM level, these services are mapped to the existing technical system landscape, including event management, customer relationship management, and document management systems. The evaluation shows that the proposed transformation model enhances semantic clarity, traceability, and structural consistency across abstraction layers.

The findings contribute to research at the intersection of BPM and MDA, particularly by addressing the underexplored transformation from CIM to PIM. From a practical perspective, the proposed model provides organizations with a structured and methodologically sound approach for modeldriven business process digitalization, supporting the alignment between business understanding and technical implementation.
