Resilience is the ability of a system, architecture, or organization to maintain critical capabilities during and following a threat or disruption. Assuring resilience can be a costly endeavor, and it requires innovative approaches in a financially constrained environment. Often these innovative approaches lead to modifications of non-materiel aspects of a system or organization; such aspects include emergency response planning, organizational culture or structure, and training. The impact of these modifications is challenging to quantify.
