Introduction and Motivation:

In today's business landscape, process management, and, by extension, process modeling play an important role in capturing, improving, and automating companies' operations. Although an array of different process modeling languages exists, many of the popular ones follow an activity-oriented paradigm, and subsequently all suffer similar limitations. Subject-oriented process modeling offers an alternative approach that emphasizes the actors involved in a process. Despite its potential advantages, subject-oriented process modeling is struggling to find adoption. One key reason for this may be the lack of available workflow engines tailored to support subject-oriented process models, which many companies rely on to manage and streamline their processes efficiently. Additionally, employees who are trained in and accustomed to an activity-oriented paradigm may find it difficult to adopt a subject-oriented mindset. Those not familiar with this way of thinking may, therefore, struggle to understand and work with subject-oriented process models.

Objectives:
To promote the adoption of subject-oriented process modeling, this thesis aims to mediate the adoption problem by examining the possibilities and limitations of transforming subject-oriented PASS models into widely used and understood activity-oriented BPMN models. Additionally, the development of a basic prototype capable of facilitating the transformation will be attempted.

Methodology:
• Conduct a literature review on core topics including BPM, S-BPM, process modeling, PASS, and BPMN.
• Compare PASS and BPMN to identify differences and overlaps.
• Outline the transformation process.
• Develop a basic prototype for transforming PASS models into BPMN using C#, Java(Script), and/or VBA, and potentially integrate it into a MS Visio-based PASS modeling tool.
