Exploring the Dynamics of Resilient Performance

Abstract : A recurring theme in studies of resilience is the need for new methods of representing system properties that focus on dynamic rather than static qualities. The goal of this thesis is to develop models that support insight into the dynamics of how resilient systems (and the people in them) manage unstable situations. It focuses on a specific but common challenge (overload), and on the strategies used to cope with it; particularly, a specific strategy, temporary stopping, in order to recover margin for maneuver. The thesis begins by an explication of the motivating case study of unexampled overload in a hospital emergency department, leading to an unprecedented system collapse. It then analyses similar cases from different settings to argue that there are isomorphisms in strategies and adaptations across levels and across domains. Finally, it develops a system dynamics model of a general work system under overload, and uses it to explore the origins of the overload crisis, and the utility of the temporary stopping strategy in managing it. It shows that a leading indicator of an impending crisis is the failure to recover fully during normally slow periods. It also shows that stopping is a potentially risky strategy, and that it is easy for actors to learn the wrong lessons from their experiences. These results can inform practical ways of anticipating and mitigating the consequences of overload in hospital settings and elsewhere.
