On Tuesday, September 20, 2016, two successful disputations of the Department of Information Systems of the University of Kassel took place in the large hall of the ITeG: 

Philipp Alexander Ebel defended his dissertation entitled "Open Business Modeling: Design and Evaluation of Artifacts for IT-enabled Business Modeling", Shkodran Zogaj defended his dissertation entitled "Governance of Crowdsourcing Systems - Managing Crowdsourcing Projects from a Crowdsourcing System Perspective". 

Professor Dr. Jan Marco Leimeister congratulated both of them on their successful disputation and presented each of them with a doctoral hat individually designed by the scientific staff of the department.

Following the successful disputations, a small champagne reception took place, which gave the two disputants the opportunity to celebrate this important milestone in their lives in the company of former colleagues, family members, friends and companions, and to exchange memories with a view to their time together at the Chair.
