The established process repository needed to be transparent, readable, and clear. In addition, it was necessary to ensure the preconditions for efficient support for the implementation of an adequate business information system for the informatization of the key processes at NIS (Pančevo Refinery). The main goal of the project was the modelling, analysis, and design for the improvement of the NIS business processes using the ARIS methodology and tools. Additional values which NIS (Pančevo Refinery) wanted to achieve with this project include the modelling of business processes, establishing of a transparent process repository to be used for the purpose of educating the employees who participate in the processes.
