Creativity is one of the vital skills for the 21th century as stated by the European Union. In our earlier work (Buijs et al, 2009) we gave a syntheses of the literature and practice on creativity resulting in an overall model for creative problem solving in groups. This model was called iCPS and consists of four interlinked sub processes Content Finding, Information Finding, Acceptance Finding and Project Management (Buijs & van der Meer,2013). Building on this work the present paper focuses on techniques that can be applied within the framework of iCPS. Based on an extensive literature study combined with the experiences of over three decades training creative facilitation of groups at the Delft University of Technology all techniques found in literature were clustered to 40 specific techniques supporting the different stages of iCPS and 8 so called session duties. 5 methods significant different than iCPS were identified. For using the 40 techniques a technique selector is proposed. The paper ends with some directions and suggestions for further research to make the shift in research on techniques for creative problem solving in groups from a merely guru driven topic to an evidence based approach.
