Sensemaking is one of the main theoretical perspectives that is used to understand both social cognition within organizational theory and the social construction of organizational behavior. Initial scholarship focused on the cognitive processes of sensemaking; discursive approaches followed in order to understand how actors come together to coordinate action. In recent years, the scope of the sensemaking perspective has expanded to account for the role of affect as well as to consider the political nature of sensemaking. Although sensemaking is most closely informed by ideas in social psychology and management, it also draws from cognitive psychology, symbolic interactionism, and ethnomethodology. The first section provides an introduction to sensemaking, including introductory works, overviews, and reviews. Next, the journals where sensemaking research is published are highlighted. This is followed by a review of the primary and emerging approaches to sensemaking. We conclude with a discussion about sensegiving, a related construct, and how a sensemaking perspective informs other areas of organizational theory, including strategic change, organizing, and symbolic approaches to organizational life.
