Interview with Yossi Sheffi, new book The Magic Conveyor Belt: Supply Chain, AI, and the Future of Work

  • 2024-08-01


Introduction: In this digital age, we are used to the convenience of placing an order with one click and receiving the goods the next day. But have you ever thought about what kind of complex "magic" is hidden behind a simple online shopping? Professor Yossi Sheffi, a master of supply chain management at MIT, has solved this mystery in his new book "Magic Conveyor Belt: Supply Chain, Artificial Intelligence and the Future of Work". This reporter had the honor of having an exclusive interview with Professor Sheffi, and discussed in depth the complexity of modern supply chains, the impact of technological innovation, and future development trends.


In the office of the Engineering Systems Department at MIT, Professor Yossi Sheffi is showing me a complex diagram. The diagram depicts the supply chain network of an average car, with dense lines connecting suppliers around the world. "See?" Professor Sheffi said, pointing to the diagram, "This is what we call the 'magic conveyor belt'."



As a journalist who has been working in the supply chain field for many years, I have interviewed many industry experts, but Professor Sheffi's views still surprise me. The concepts proposed in his new book "Magic Conveyor Belt: Supply Chain, Artificial Intelligence and the Future of Work" are challenging our traditional understanding of modern business operations.

"An ordinary car contains about 30,000 parts," Professor Sheffi explained, "These parts come from suppliers around the world, and many parts will travel back and forth between multiple continents before final assembly. Each part needs to be carefully designed, selected from specific materials, carefully manufactured, and then delivered in a timely manner."

As a reporter who often covers the automotive industry, I am well aware of the complexity of automobile manufacturing. But Professor Sheffi's next words still surprised me: "Did you know? Even a seemingly simple baby diaper contains more than 50 parts." Professor Sheffi emphasized that the efficient operation of the supply chain depends on the decentralized nature. "There is no central control system managing the entire supply chain," he said, "Every participant is working hard to reduce costs and improve service levels. Through countless negotiations and transactions between buyers and sellers, the entire system can operate."

This reminds me of Adam Smith's "invisible hand" theory. Professor Sheffi nodded in agreement: "Yes, the operation of the supply chain is the modern embodiment of the 'invisible hand.'" However, this complexity also brings challenges. For example, the problem of visibility. "Companies usually only know their first-tier suppliers," Professor Sheffi explained, "but these suppliers also have their own suppliers, and these second-tier and third-tier suppliers are often opaque." This opacity can lead to unexpected risks, such as quality problems or ethical issues deep in the supply chain.

Nevertheless, Professor Sheffi believes that this complexity is inevitable and even necessary. "Complexity brings more possibilities," he said, "and more possibilities create more complexity. It's a virtuous circle."

In general, the modern supply chain is like a sophisticated ecosystem, and every participant plays his or her role. It is this seemingly chaotic but highly coordinated operation that allows us to buy products from all over the world at amazingly low prices. The next time you pick up an item in the store, imagine the "magic conveyor belt" behind it, and I believe you will be in awe of this miraculous system.

To help me better understand the complexity of the supply chain, Professor Sheffi explained it in detail using the example of bananas. From the plantations in Costa Rica to the supermarkets in Boston, bananas have to go through multiple links such as picking, cleaning, transportation, shipping, and distribution. The most interesting thing is that retailers need bananas of different degrees of maturity to meet consumer demand, so bananas also go through a precisely controlled artificial ripening process. "Next time you see bananas neatly arranged on the shelves in the supermarket," Professor Sheffi said, "I hope you can think of the 'magic conveyor belt' behind it. People should not be angry because something is not on the shelf, but should be amazed and awed that the goods can be there."

As a veteran supply chain reporter, I have to admit that Professor Sheffi's views have given me a new understanding of this industry that I thought I was very familiar with. The complexity and precision of the modern supply chain can indeed be called "magic".


Challenges and opportunities of global supply chain


In this interconnected world, supply chains have long crossed borders and formed a complex network covering the globe. But in recent years, geopolitical developments, changes in trade policies, and growing concerns about environmental and social responsibility are driving companies to rethink their global supply chain strategies. Professor Xie Fei, with his unique insight, analyzes this complex situation for us.

"Globalization has brought unprecedented opportunities, but it also brings risks," Professor Xie Fei said straight to the point, "The question now is how to improve the resilience and sustainability of supply chains while enjoying the dividends of globalization."

Let's first look at the advantages of globalization. Professor Xie Fei reminds us not to forget the positive impact of globalization: "In just a few decades, China has rescued 800 million people from extreme poverty and promoted them to the middle class. This is an unprecedented humanitarian achievement."

Globalization allows companies to use comparative advantages to find the best resources and production sites around the world. Professor Xie Fei explained: "It's not just about cost. China now has the best infrastructure in the world, well-trained engineers, and a complete supply chain ecosystem. This is why many companies choose to stay in China even if labor costs rise."

However, globalization also brings challenges. Professor Sheffi noted: "When your supply chain is spread across the globe, you are more vulnerable to geopolitical risks, natural disasters and other unforeseen events."

The COVID-19 pandemic is undoubtedly a turning point. "The pandemic exposed the fragility of global supply chains," Professor Sheffi said. "Suddenly, companies realized that they were much more dependent on certain key suppliers than they thought. 

This realization has driven the trend of nearshoring and relocalization. But Professor Xie Fei is cautious about this: "It's easier said than done. Companies have spent decades and billions of dollars to build a complete supply chain ecosystem in China. You can't just move it all away easily."

He gave an example: "Some companies did move the final assembly to Vietnam, but 99% of the value still comes from China. This is more to meet certain political requirements rather than a real supply chain value transfer."

Professor Xie Fei also pointed out some practical challenges facing re-localization: "For example, in the United States, we have more rare earth deposits than China, but we don't mine because of environmental issues. This is where we need to weigh - national security, environmental protection, economic benefits, how do we find a balance between these goals?"

Regarding the impact of trade policy on the supply chain, Professor Xie Fei made an interesting point: "Politicians like to say we want to punish China, but in fact, tariffs are ultimately paid by domestic consumers. Every tariff may trigger countermeasures from the other side, ultimately leading to reduced trade and making everyone worse off."

So, in the face of these challenges, how should companies respond? Professor Xie Fei gave some suggestions:

Diversification strategy: "Don't put all your eggs in one basket. Look for multiple sources of supply, especially for key components."

Improve visibility: "Try to understand your deep supply chain. Although complete transparency is difficult to achieve, at least know who your key suppliers' suppliers are."

Flexibility: "Establish a supply chain system that can respond quickly to changes. This may mean sacrificing some efficiency in some cases in exchange for greater flexibility."

Localization and globalization: "Consider adopting a 'multi-region' strategy and establishing a relatively complete supply chain in different regions, which can not only enjoy the benefits of globalization but also reduce risks."

Focus on sustainability: "More and more consumers and investors are paying attention to the environmental and social responsibilities of companies. Incorporating sustainability into supply chain strategies is not only the right thing to do, but also a wise move in the long run."

Professor Xie Fei particularly emphasized the importance of system thinking: "We can't just focus on one aspect. National security, environmental protection, economic development, these are all factors we need to consider at the same time. Unfortunately, whether in politics or the media, there are too few people who can really think systematically."

Finally, Professor Xie Fei concluded with a vivid metaphor: "Managing a global supply chain is like riding a bicycle. You need to constantly adjust your balance and adapt to the ever-changing terrain. If you stop, you will fall, but as long as you keep moving forward, you can find balance in a complex environment."

In this era of uncertainty, the balance between globalization and localization is undoubtedly a major challenge facing every supply chain manager. But as Professor Xie Fei said, challenges also contain opportunities. Those companies that can respond flexibly and balance efficiency and resilience will stand out in future competition.


Technological innovation drives supply chain development


Walking into MIT's Supply Chain Innovation Lab, I felt like I was in the future. Various advanced sensors, robots, and smart devices are simulating the operation of modern supply chains. Professor Sheffi stood in front of a huge touch screen and showed me the evolution of supply chain management technology.

"We can divide the technological development of supply chain management into four stages," Professor Sheffi said, "which corresponds to the four stages of the industrial revolution." He then explained in detail the mechanized production from the first industrial revolution to the widespread application of the Internet of Things and artificial intelligence in the current fourth industrial revolution.

As a reporter who often reports on technological innovation, I was particularly interested in several key technologies mentioned by Professor Sheffi. "The introduction of barcodes was an important milestone," Professor Sheffi said, "it greatly reduced the workload of inventory management and laid the foundation for automated ordering systems."

I was reminded of the sensation caused by the introduction of barcode scanning systems in supermarkets in the 1970s. "Yes," Professor Sheffi smiled, "it seems to be a simple technology now, but it has completely changed the retail industry and supply chain management."

Professor Sheffi then talked about the impact of technologies such as EDI (electronic data interchange), GPS, and RFID. "RFID was once thought to completely replace barcodes," he said, "but in fact it has only played an important role in certain specific areas. This reminds us that technology predictions are not always accurate."

As a journalist who has misjudged some technology trends, I was deeply touched by Professor Sheffi's words. I asked him to give an example of the unexpected consequences that technological innovation may bring.

Professor Sheffi thought for a moment and said: "Remember how popular the word 'blockchain' was a few years ago? Many companies claimed to use blockchain to solve supply chain problems. The result? Most projects did not achieve the expected goals. This is not to say that blockchain has no value, but we need to be more cautious in evaluating the actual application potential of new technologies."

Speaking of cloud computing, Professor Sheffi pointed out: "Cloud computing has greatly reduced the cost of information processing and storage and improved the efficiency of supply chain collaboration. Now, even small businesses can use advanced supply chain management software."

To illustrate how technological innovation can completely change an industry, Professor Sheffi used FedEx as an example. "FedEx founder Fred Smith predicted in 1978 that 'package information will be as valuable as the package itself'," said Professor Sheffi, "This insight led to the transformation of the entire express delivery industry."

As a reporter who once interviewed Fred Smith, I was impressed by FedEx's innovation process. Professor Sheffi's analysis gave me a new understanding of the company.

When it comes to the application of artificial intelligence in the supply chain, Professor Sheffi is particularly excited. "AI is changing many areas of supply chain management," he said, "from risk management to demand forecasting to customer service, the impact of AI is everywhere."

He specifically mentioned a company called Resilinc, which uses AI technology to monitor tens of thousands of suppliers in real time and analyze risk signals in media reports. "This technology can help companies detect potential supply chain risks months in advance," Professor Sheffi explained.

However, Professor Sheffi also emphasized that technology is not omnipotent. "The key to future supply chain management lies in human-machine collaboration," he said, "We need to cultivate sophisticated users who can understand the potential and limitations of AI, rather than builders of AI systems."

To further illustrate the importance of human-machine collaboration, Professor Sheffi took me to visit a simulated warehouse in the laboratory. "Look here," he said, pointing to a workstation, "workers stand in fixed positions while shelves automatically move to them. Machines are responsible for repetitive movement work, and humans are responsible for picking work that requires judgment. This is a good example of human-machine collaboration."

When I left the laboratory, I deeply felt the tremendous changes that technological innovation has brought to supply chain management.


How to work in the AI era


"The future is already here, it's just not evenly distributed." This sentence is particularly apt in the field of supply chain management. With the rapid development of artificial intelligence (AI) and automation technology, the work of supply chain management is undergoing earth-shaking changes. Professor Xie Fei painted a picture of the future for us that is full of opportunities and challenges. "

First, we must understand that AI is not here to replace humans, but to enhance human capabilities," Professor Sheffi said straight to the point, "The most successful supply chain managers in the future will be those who can effectively use AI while leveraging the unique advantages of humans."

Professor Sheffi emphasized that future supply chain management will be an era of human-machine collaboration: "Machines are good at processing large amounts of data and repetitive tasks, while humans are good at handling situations that require empathy, creativity, and judgment. The key is to find the best combination."

He gave an example: "Imagine an Amazon warehouse. Pickers stand in place and shelves automatically come to them. This is a great example of human-machine collaboration. Machines handle heavy physical labor, while humans are responsible for tasks that require flexibility and judgment." Professor Sheffi predicted that more such work modes will appear in the future: "We may see more 'human-in-the-loop' systems, where AI handles most of the work, but humans are required to intervene at key decision points."

Facing such a future, what capabilities do supply chain managers need? Professor Sheffi gave the following suggestions:

Technical literacy: "You don't need to be a programmer, but you need to understand the basic principles, capabilities, and limitations of AI."

System thinking: "The supply chain is a complex system, and you need to be able to see the big picture and understand how the parts interact."

Adaptability and learning: "The pace of technological change will only get faster, and lifelong learning will become a necessity."

Communication and collaboration skills: "As work becomes more cross-functional and cross-cultural, these 'soft skills' will become increasingly important."

Creative problem solving: "AI can provide data and analysis, but humans are still needed to apply these insights creatively."

Ethical judgment: "As AI plays an increasingly important role in decision-making, it will become an important responsibility of managers to ensure that these decisions are ethical and in line with corporate values."

Professor Xie Fei believes that in order to cultivate such talents, the education and training system also needs to change accordingly: "Our education program has changed," he said. "In the past, we focused a lot on analytical skills, but we found that graduates often lost to those with stronger soft skills in the workplace. So now we focus more on cultivating communication, teamwork and other abilities."

Professor Xie Fei also mentioned the concept of "dual education": "Germany has a good model where students spend half of their time working in a company and half of their time studying at university. This This model allows students to better combine theoretical knowledge with practice. "

For working people, Professor Sheffi stressed the importance of continuous learning: "Companies need to invest in upgrading the skills of their employees. But the greater challenge is for independent workers and small businesses, who may not have the resources for training. This may require government support. "Professor Sheffi admitted that this transition is not without challenges: "It is understandable that people are anxious about their jobs being replaced by AI. But history tells us that technological progress ultimately creates more jobs than it eliminates. "

He gave an example: "Who would have thought that there would be jobs like 'Google Ads Optimizer' decades ago? New technologies always bring new job opportunities. "

But Professor Sheffi also warned that this transition may exacerbate inequality: "Those who can adapt to new technologies may get more opportunities, while those who cannot adapt may be left behind. This is a challenge we need to face together as a society. "

Looking to the future, Professor Sheffi is full of hope: "Supply chain management in the AI era will be more efficient, smarter and more sustainable. But most importantly, it will provide exciting career opportunities for those who are willing to embrace change and keep learning. He ended our conversation with a vivid metaphor: “Managing a supply chain is like sailing a large ship. AI and automation are our new navigation systems and engines, but we still need experienced captains to steer the ship. The future belongs to those who can skillfully use these new tools while retaining uniquely human insight.”
