= Drift-to-danger Model = The '''drift-to-danger model''' is a dynamic model for understanding workplace safety. <> ---- == Description == In brief: * A system is established with goals and constraints, e.g. a factory has N staff and targets Y output and has various workplace safety policies. * Individuals form strategies for how to meet goals and constraints balancing their effort. * As circumstances change, so too do individuals' strategies; certain changes can cause strategies to drift towards danger, e.g neglect of safety policies. * A well functioning system requires defenses in depth--systems as independent layers that will react to transgressions and provide a negative feedback signal. * A highly complex system (i.e. many layers) also requires a coordinating agent that is familiar with all layers and can identify accumulating transgressions. * A complex system fails when too many layers have transgressed and or failed to provide negative feedback. ---- == Reading Notes == * [[RiskManagementInADynamicSociety|Risk management in a dynamic society: a modelling problem]], Jens Rasmussen, 1997 ---- CategoryRicottone
