In this paper, we present a case study research on designing the system interface for handling organisational processes implemented in the editorial office of the AGH-UST Students Information Bulletin. A study of the basic formal and legal sources, such as regulations and statutes of the organisation, was also carried out for the proper identification of goals, responsibilities, and organisational structure. To deepen this knowledge, social research was carried out, which examined how the users use the current solutions and what their needs are related to the designed system. Based on the research results and the formulated conclusions, the diagrams of business processes carried out in the organisation were created. In the discovered process models, we defined reusable sub-processes using Justified Aggregation of Neighboring Activities. Finally, the information architecture of the target system solution, followed by a mediumfidelity interface were designed.
