In the past decades, the world has witnessed the rising importance of global supply chains along with outsourcing productions and services. What in your view have been the main consequences of this phenomenon for businesses?
Global supply chains have been increasingly relying on low cost manufacturing from overseas sources. This trend has been occurring for the last thirty to fifty years. Much of the activity has been driven by the continued pressure to buy products and sell them at the lowest possible cost. Accordingly, many companies moved their manufacturing to low cost regions to gain on labor costs, which was often the highest contributor to the total costs. This wave of offshoring was enabled by international trade agreements struck between nation states aimed to reduce duties and taxes.
Offshoring the production often meant that firms would establish large and centralized production facilities to exploit volume advantages and locations often as China, India, Thailand and Vietnam etc. The final product is manufactured in centralized facilities, and is shipped around the globe to large distribution centers in the U.S. or in Europe largely through ocean freight. The product is distributed with significant markups to large retailers. This practice was encouraged by consumers who voted with their dollars and pay for the lowest price and for the large brands and retailers.
Did this trend accelerate by the fall of the command and control type economies?
Absolutely, this was another major driver. As the Eastern Block opened up to broader economic reforms, they no longer did as much manufacturing within their own countries. The formation of the European Union also led to greater outsourcing to lower cost regions. Buying on the basis of low cost and price became the predominant force of offshoring in these low cost countries. Unfortunately, they did not consider associated with doing so.
What are the trade-offs of low costs and worldwide long supply chains?
There are some significant trade-offs. First, there is a lack of direct oversight over the whole operation. You are more likely to have quality problems and less control over the labor force, which allows the abuse of labor and in some cases even led to slavery. On the other hand, most of the shipments were made by ocean freight and the lead times for these became longer and longer, while the ships became larger and larger. They made more frequent stops, they slowed down what they call slow steaming. As a result, companies have a lot inventories on the water. That meant they had to increase the inventory they had on hand because the lead times were so long. It also exposed us to additional disruption such Brexit or the US – China trade war on tariffs, which lead to supply being constrained. However, one of the biggest risks completely overlooked was the possibility of export control and product shortages with cut off supplies in critical material such as medical supplies. So the chickens have come home to roost in early 2020. What I also observed in this situation that it is very difficult to have visibility into material that was in the supply chain. It would go into ports, it would go into custom locations, it would be on a ship but you did not really know where it was. You just have to sit and have to wait and you hoped that it has got here as quickly as possible. That created a lot of problems.
