This chapter is based on the author’s research on group creativity and educational initiatives in the private and public sectors as well as in higher education courses at an advanced level. The contribution is derived from both qualitative and quantitative methodological approaches to present in-depth knowledge of creative collaboration and competence as well as training of the necessary skills needed to activate both the prerequisites and predictors for creativity. Research shows correlations between experiences of flow in idea-generating group activities and group members’ integrative social behavior. In addition, it is shown that training for increased divergent thinking also develops broadened attention, openness, and flexibility for perspective shifts. A conceptual framework is presented to construct a model of research design on collaborative creativity with the purpose of enabling comparisons between study’s methodology and findings to continue developing this field of research with joint efforts. The chapter advances the view that the impact of activities training group-based creativity should be elevated in importance beyond individual brilliant ideas because creative collaboration develops abilities to take initiative, make decisions and interact constructively together
