Adam DeJans Jr. shared a great post about why he loves supply chain. “Supply chain is one of the few fields where the problem looks simple on paper and then immediately becomes impossible the moment it touches reality. Move the right product, to the right place, at the right time, at the right cost. That sounds easy until you realize every word in that sentence hides a war. The “right product” depends on demand that is uncertain. The “right place” depends on networks, capacity, labor, transportation, inventory positioning, and service promises. The “right time” depends on lead times, supplier behavior, weather, ports, trucks, warehouses, and human decisions. The “right cost” depends on tradeoffs that are almost never visible in a spreadsheet until someone makes the wrong decision and the business feels it.

That is why I love supply chain. It is not just forecasting. It is not just optimization. It is not just operations. It is economics, uncertainty, negotiation, incentives, systems design, human behavior, and math all colliding at once. A supply chain is basically a living organism where every decision creates a reaction somewhere else.” Link
