In this episode, Ron and Joseph call into question the body of knowledge that is the basis of the discipline of supply chain as it exists today.
Keeping in mind that the modern supply chain has existed for roughly 30 years, with the fall of the Berlin Wall, the ascent of China, the building of super-sized container ships, it could be argued that the basis of our knowledge is in need of being challenged and updating with the experiences gained; especially from recent events.
And perhaps supply chain and logistics experts (and academia) need to make sure they have experience where the action happens; on the docks, at the ports, in the trucks (going to the gemba, in Lean parlance). This will contextualize the reality of what is going on and bring to life what is being seen on screens.
Sometimes, you have to go backwards to go forward.
