In order to increase the diversity in IS education, we discuss an approach for teaching medium-sized ERP systems in university courses. Many of today's IS curricula are biased toward a few large ERP packages. Nevertheless, these ERP systems are only a part of the ERP market. Therefore, this paper describes a course outline for an additional course on medium-sized ERP systems. Students had to study, analyze, and compare different ERP systems on their own during a semester. The seminar took place at three universities at the same time. The paper introduces a procedure model and a scenario for setting up similar courses at other universities. Furthermore, it discusses some of the students' outcomes and evaluates the contribution of the course with regard to a practical but also academic IS education in a comparison of the three universities.
