In recent years, domestic institutions, including hospitals, have been increasingly focusingattention on organizational and human resilience. This study explored basic knowledge on and methods for developing organizational and human resilience. This study used the internationally recognized Bloomberg’s COVID Resilience Ranking as the basis for explaining the diversity of resilience and performed a literature review to explore the findings of research in related disciplines of organizational resilience, human resilience, and resilience engineering. Although human and organizational resilience differ in terms of objects and goals, according to system concepts, both individuals and organizations exhibit the system properties of hierarchy and emergence, and individuals are an element of the organization. To overcome challenges encountered by medical institutions in developing the two types of resilience, this study proposes planning with reference to system concepts, models, promotion frameworks, design principles, and resilience engineering tools and integrating human and organizational resilience for overall development.
