  1. 1. 1/23 www.janclaes.info FACULTY OF ECONOMICS AND BUSINESS ADMINISTRATION Jan Claes Teaching assistant : PhD 2009 – 2015 Supervisors : Geert Poels & Frederik Gailly Why do people struggle with the complexity of constructing a process model?

  3. 3. 3/23 www.janclaes.info Business Process Modeling (BPM) Assumptions  Constructing process models is useful  Process model quality is important Business Process Modeling (BPM)  Process model quality “what is a good process model?”  Process of process modeling (PPM) “how to make a good process model?”
