This year's traditional summer party of the Department of Information Systems (Prof. Dr. Jan Marco Leimeister) at the University of Kassel took place on July 3, 2019. The program this time included joint sports activities of the team including a paddling competition. In the evening, the actual summer party including department alumni and student assistants took place in a boathouse at the Fulda river in the Karlsaue park landscape. Over drinks and barbecue, the first half of 2019 was reviewed by the attending department staff, alumni and student assistants in a cozy atmosphere. Enclosed are a few photo impressions of this traditional event, which has had a fixed place in the calendar of the Department of Information Systems for many years.
