This paper presents the concept of business unit to model business processes. A business unit’s main strength is that it represents resources like personnel and time that business processes consume at run-time. Due to concerns of resource scarcity and unavailability, their consumption is controlled using policies expressed in Open Digital Rights Language (ODRL) in this paper. In addition to policies, ODRL integrates permission, prohibition, and obligation rules that define how, when, where, and by whom resources are consumed. Parsing resources’ ODRL policies results in extracting the necessary business units that are the future building blocks of business processes. The technical doability of business unit-based modeling of business processes is also demonstrated in the paper using a Large-Language-Model (LLM).
