We designed a simulation game to work with and experiment with the design principles for knowledge productivity. Recently we met Frans van Gassel, from the Technical University in Eindhoven (TU/E), and he invited us to collaborate with him to prepare a game for the 4th symposium on Value Development in Construction Management. The students-association of Course takes the initiative for this conference together with the Masterprogramma Construction Management and Engineering (Frans van Gassel). The game takes place at June 7, in the morning. In the afternoon some lecturers (my colleague Paul Keursten is one of them!) will reflect on the symposium's main theme 'creatief vragen en aanbieden', Paul Keursten in his speech will reflect upon the morning programma where we worked with the design principles.
