Planning and organizing their studies by selecting modules and the order in which to attend them is an important challenge for students. Bachelor students, in particular, usually perceive this as an obstacle [1]. However, universities rarely provide tools to support students in this decision-making process. Using the method of qualitative interviews, this paper elicits requirements for a digital tool that supports the process of study planning for computer science students at the University of Bamberg, Germany. The resulting requirements are used as a foundation for a prototypical implementation. Based on this prototype, the feasibility of the collected requirements is analyzed and potential further developments are discussed.
