EXPRESS: We are all pattern makers! How a flat ontology connects organizational routines and grand challenges

Adopting a flat ontology, we discuss how phenomena of societal concern are connected to organizational routines. We conceptualize grand challenges as large patterns of actions to overcome the micro-macro divide prevalent in existing research. We introduce spatial, temporal, and agentic relations as three interrelated aspects of scale that are of particular interest and demonstrate how social phenomena may be approached through these relations. Focusing on the situated enactment of routines allows us to identify weakening and strengthening between actors and their actions as important processes that reflect the continuous patterning of grand challenges. We contribute to the literature by highlighting the consequentiality of mundane actions and by questioning the dominant approach to change in research on grand challenges. Our insights offer several practical implications for intervening on grand challenges.
