Institutions - the structures, practices, and meanings that define what people and organizations think, do, and aspire to - are created through process. They are 'work in progress' that involves continual efforts to maintain, modify, or disturb them. Institutional logics are also in motion, holding varying degrees of dominance that change over time. This volume brings together two streams of thought within organization theory - institutional theory and process perspective - to advocate for stronger process ontology that highlights institutions as emergent, generative, political, and social. A stronger process view allows us to challenge our understanding of central concepts within institutional theory, such as 'loose coupling', 'institutional work', the work of institutional logics on the ground, and institutionalization between diffusion and translation. Enriched with an emphasis on practice and widened by taking a broad view of institutions, this volume draws on the Ninth International Symposium on Process Organization Studies to offer key insights that will inform our thinking of institutions as processes.
