In contrast, the simple router supply chain is also global but is focused on cost efficiency. Less product variation permits higher velocity, but at the same time lowers elasticity within the supply chain. This kind of supply chain can be less adaptive to operational changes. When a disruptive event happens, problems might ripple widely and rapidly through the system. By being aware of these vulnerabilities, Cisco knew how to implement mitigation measures to make this kind of supply chain more resilient, too.
