ISIS Papyrus, founded in 1988 and based in Brunn am Gebirge, Austria, operates within the software industry, specifically focusing on Customer Relationship Management (CRM) software. The company employs between 201 and 500 individuals and reported a revenue of approximately 47 million USD. ISIS Papyrus is engaged in research and development related to business process management (BPM) and adaptive case management (ACM), emphasizing the need for flexibility in managing dynamic and knowledge-intensive business processes. A recent document published by the company discusses the transition from traditional BPM methodologies, such as Business Process Model and Notation (BPMN), to a declarative, rule-based ACM approach. This research highlights the strengths and limitations of both modeling techniques, providing insights that can assist practitioners and researchers in effectively designing and managing business processes that require adaptability to unforeseen situations. The findings aim to enhance the understanding and implementation of dynamic management strategies within organizations.
