The chapter entitled “The Practice of Participatory Enterprise Modelling – a Competency Perspective” by Anne Persson addresses the question of how to develop enterprise models in a participatory way, in particular which competencies that are required for this purpose. The chapter presents the two main ways of working when it comes to involving stakeholders in the modelling process, the participatory and the non-participatory, and then focuses on the participatory approach. The author describes the desired competencies of domain experts and method experts, which are two of the most crucial actors in the participatory modelling process. The author further argues that although competency is one of the most critical success factors in modelling it is an overlooked topic in modelling research. The chapter is illustrated with quotes from an interview study that the author has carried out.
