Complex decision-making, intelligence of the crowd, societal transitions, human resource management, and system innovation. Harry has pioneered in societal transition thinking for 25 years. Educated as a product design engineer (Delft University of Technology) and having worked as a product design manager (TNO applied research), as a management consultant (Twijnstra Group), and as interface science/society (Erasmus University/DRIFT), he now clarifies people's positions during deep change. His mission: to reduce psychological, social, material, and economic damage caused by societal system shifts. He puts focus on the human resource - can people play their roles to the fullest when change gets tough? He masters activating intelligence of the crowd for complex decision-making and works in a variety of domains: agriculture&food, the energy transition, the monetary system, political decision making, education, spatial planning, and others. He has become an expert in next level participation processes and typically works for governments, though masterclasses and lectures for mixed audiences, columns for magazines, podcasts, and coaching sessions for explorative minds can be expected. In close co-operation with Esther van der Valk, Harry runs Transitiefocus ('comfortably out of control').
