Adaption-Innovation theory (A-I theory) is a model of problem solving and creativity, which aims to increase collaboration and reduce conflict within groups. A-I Theory and the associated Kirton Adaption-Innovation (KAI) inventory have been extensively researched and are increasingly used as tools for teambuilding and personnel management. In Adaption-Innovation: In the Context of Change and Diversity, Kirton outlines the central concepts of the theory, including the processes of problem solving, decision making and creativity.
