Why is there a demand for consultants and outside directors? That is because what they are asked for objective advice and the clue—this chapter describes them as external activate factors—is precious. This chapter focuses on how the external activate factor affects human creativity, especially the process of creating new products or services, and the author conducted an experiment to compare the effect of external activate factors at a lecture of graduate school. As a result, when the external activate factor is provided, the emergence of abduction and new rules was observed, and the effect of storytelling was confirmed. Further research is to find what kind of external activate factor is preferable.
