According to the CTSC Exam Content Manual1, one of the key capabilities for supply chain resilience is agility, which is the ability to respond quickly and effectively to unanticipated disruptions. Agility enables supply chain professionals to adapt to changing customer needs, market conditions, and operational challenges. Another key capability for supply chain resilience is velocity, which is the speed at which products and information flow through the supply chain. Velocity enables supply chain professionals to reduce lead times, improve service levels, and increase customer satisfaction. Therefore, increasing levels of agility and velocity is a measure that should be adopted for supply chains to become more resilient to unanticipated disruptions. Option A, implementing internal standards of risk awareness and response, is a measure that can help mitigate the impact of disruptions, but it does not necessarily increase the resilience of the supply chain. Option B, ensuring that there is clear responsibility for identifying risk, is a measure that can help prevent or reduce the likelihood of disruptions, but it does not necessarily increase the resilience of the supply chain. Option C, decreasing inventory levels to the minimum level possible, is a measure that can reduce costs and waste, but it can also increase the vulnerability of the supply chain to disruptions.
