The notations of the Object Management Group (OMG) in the area of business process management have become the de facto standard. In addition to a purely technical description, the OMG notations also offer the possibility of digitalization. However, it is not enough to know the symbol palettes of BPMN, DMN and CMMN. A targeted approach to the description of business processes, rules and cases ensures transparency, traceability and acceptance of the modeling of the tactical level in the enterprise. In our trainings we convey our practical experience from the implementation of a large number of successfully implemented projects.
