The paper covers the authors' research in improving business and IT process modeling. Practical experience shows that universal modeling languages such as UML and BPMN are IT oriented and are difficult to accept by business people. Business models need to use such hard to formalize business terms as legal acts, informal activities descriptions and comments etc. They propose novel approach how to create or choose modeling tools according to model usage. They propose 4 usages for modeling: model to understand business processes, model for business process definition, model as information system specification and model that can be interpreted by computer.
