Just-in-time networks are efficient but the recent Coronavirus Outbreak has illustrated that this is also an extremely fragile state of engagement with key suppliers. Great article from Bloomberg that explores
The global supply chain, already under pressure from President Donald Trump’s trade war, now faces further strain from the coronavirus. And while cross-national supply chains are more robust than they may appear, if they fail they will do so suddenly and without much warning.
Consider the supply chain of the Apple iPhone, which stretches across dozens of companies and several continents. Such complex cross-national supply chains generate relatively high profits, giving them a kind of immunity to small disruptions. If there is an unexpected tax, tariff or exchange movement, the supply chain can generally swallow the costs and move on. Profits will be lower within the supply chain, but production will continue, as it is too lucrative to simply shut everything down.
Do not be deceived, however: Supply chains are not indestructible. If the new costs or risks are high enough, the entire structure will be dismantled. By their nature, supply chains do not fall apart slowly, because each part of the chain relies upon other parts to add its value. It does not help much to have the circuit components of the iPhone lined up, for instance, if you cannot also produce the glass screens. In this way, these supply chains are less robust under extreme conditions.
