For my PhD research I studied several large software product development organizations to get a better understanding flow and impediments. Flow-based development is a rich and growing field with many concepts; the specific focus for this study is impediments to flow. This study takes the perspective that organizations are complex adaptive systems. This research uses sensemaking to get a richer, more-informed understanding of flow, impediments, and the context and culture of the organizations that are experiencing impediments to flow. The organizations that are part of this study are all large software product development organizations. The focus of this study, then, narrows to managing impediments to flow in large software product development organizations, using a sensemaking and complexity perspective.
