 People try to make sense of organizations, and organizations themselves try to make sense of their environment.In this sense-making, Weick pays attention to questions of ambiguity and uncertainty, known as "equivocality" in organizational research that adopts information processing theory.His contributions to the theory of sensemaking include research papers such as his detailed analysis of the breakdown of sensemaking in the case of the Mann Gulch disaster, in which he defines the notion of a 'cosmology episode' - a challenge to assumptions that causes participants to question their own capacity to act.
