Networks and Cities in a Dynamic Society

The scope of practice and theory of ergonomics is expanding, and large socio-technical systems such as cities are now being investigated using ergonomics methods. Within this context the value of Rasmussen's [1] dynamic risk model is even more apparent. However, as complexity increases, so must ergonomics' adaptability both in its concepts and methods. Therefore, this paper argues that an expansion of the mental model proposed by Rasmussen [1] through the explicit inclusion of social network and stakeholder analysis concepts and methods is warranted. This is because these concepts provide valuable insight into how cities and communities maintain their sustainability and resilience over time. The paper closes by providing an example of how the model assists ergonomists in thinking about city-level dynamics and their influence upon stakeholders.
