This study explores the antecedents of knowledge utilization, specifically tacit knowledge, leading to improvisation in rescue projects confronted with turbulent situations. We used semistructured interviews and observations to collect data in a large public-sector rescue organization. Findings reveal that improvisation is an essential part of projects in turbulent situations bounded by time limitations; resource constraint factors, such as lack of technology, information, resources, and rugged terrains; and collectivistic societal and cultural issues. Rescue workers improvise through sensemaking, problem identification, and tacit knowledge utilization to handle emergencies.
