Three case studies that illuminate the careers of organizing visions also help us understand important case boundary choices characteristic of this type of research. The choices involve: time frames, cast of characters, action focus, observational means, lines of interpretation, and contextual anchors. We argue that these choices are best regarded as open-ended and provisional, subject to being reconsidered over the course of a study, to maximize insights gained. We relate the choices to major challenges in making cumulative research progress from studies of organizing vision careers
