Safe, thriving, and sustainable communities rely on infrastructure systems delivering uninterrupted levels of service, to provide for their essential needs.

These systems are exponentially increasing in interconnectivity and complexity, and communities expect these systems to continue to function in both business-as-usual times, and during unforeseen events – despite the frequency and intensity of these events increasing due to climate change.

In order to manage this resilience challenge with the limited resources we have, we must focus our attention on the most critical elements of our infrastructure systems. Given the advancements in technology and data collation there are now greatly improved and more holistic ways of thinking about criticality.

This paper reviews current methods of assessing criticality and proposes a number of improvements, drawing on recent research into infrastructure interdependencies, and utilising the power of geospatial tools. In particular, we explore criticality from the point of view of community impact, environmental impact, complexity of repair, social vulnerability and various forms of interdependency.
