The paper is devoted to the utilization of DEMO enterprise ontology (Design & Engineering Methodology for Organizations) for refactoring purposes in software development. The main contribution of the paper resides in presentation of the method which interconnects ontological models of business processes with information system features implementation. Also, it allows the evaluation of their relevancy for enterprise. In contrast to other methods based on best practices, the proposal uses ontological description of business processes defined upon the theory in DEMO methodology. This makes the proposal unique compared to other approaches. Moreover, it provides a clear differentiation of features which are important for performing tasks by employees in company.
