This Element presents and discusses the main trajectories in the evolution of the concept of ambiguity and the most relevant theoretical contributions developed around it. It specifically elaborates on both the intrinsic perspectives on ambiguity as an inherent part of organizational decision-making processes and the more recent strategic perspectives on discursively constructed strategic ambiguity. It helps illuminate the path ahead of organizational scholars and offers new avenues for future research. This is important given the ever more pervasive presence of ambiguity in and around organizations and societies.
