This highly interactive workshop will focus on introducing participants to the existing research and teaching materials on effectuation. Effectuation consists of a set of heuristics and tactics used by expert entrepreneurs culled from a cognitive science-based study of founders of companies in a wide variety of industries. The ventures these entrepreneurs had founded ranged in size from $200 million to $6.5 billion. The principles of effectuation constitute an inversion of ideas commonly assumed to be at the core of entrepreneurship. The research that led to the development of effectual logic involves over a dozen scholars from around the world and about a decade of data gathering using several different methods. Currently about a hundred educators around the world are teaching effectuation and also developing teaching materials, many of which are now available through the textbook Effectual Entrepreneurship as well as through www.effectuation.org.
