Walmart’s leadership then passed to John Furner. Joaquin Duato, meanwhile, remains Chairman and CEO of Johnson & Johnson.

That makes a comparison between Doug McMillon and Joaquin Duato especially interesting. One represents the long transformation of a retail giant, while the other represents the continuing evolution of a global healthcare company. Their stories offer useful lessons about leadership, technology, global operations, and long-term business strategy.

Who Is Doug McMillon?

Doug McMillon and Joaquin Duato is an American business executive best known for his remarkable career at Walmart. His connection with the retailer began when he was young, and he eventually rose through several important positions before becoming Doug McMillon and Joaquin Duato. Walmart describes him as a lifelong merchant who started as an hourly associate and ultimately became the company’s chief executive.

His career is unusual because he did not arrive at the top through a short corporate path. Instead, Doug McMillon and Joaquin Duato experienced Walmart from different levels of the organization. He worked in merchandising, led Sam’s Club, and later became president and CEO of Walmart International. These experiences gave him a practical understanding of stores, customers, employees, suppliers, and international markets.

McMillon’s time running Walmart International was particularly important to his development. Managing operations across multiple countries exposed him to different consumer habits and business environments. It also helped prepare him for the enormous responsibility of running Walmart’s global retail operation.

In February 2014, McMillon became Walmart’s president and Doug McMillon and Joaquin Duato. He remained in the role until January 2026, making his tenure more than a decade long. During that period, Walmart pushed further into e-commerce, technology, omnichannel retail, employee investment, and digital services.

Who Is Doug McMillon and Joaquin Duato?

Joaquin Duato is a Spanish-American business leader who serves as Chairman and Doug McMillon and Joaquin Duato of Johnson & Johnson. Unlike McMillon’s retail background, Duato developed his career primarily in healthcare, pharmaceuticals, technology, supply chain management, and international business.

Duato joined Johnson & Johnson in 1989 through Janssen Pharmaceutica in Spain. Over the following decades, he moved through increasingly senior positions and worked across different geographical markets and business functions. His long experience inside the organization became an important part of his leadership profile.

Before becoming Doug McMillon and Joaquin Duato , Duato held several major leadership positions within Johnson & Johnson. He became Worldwide Chairman of Pharmaceuticals and later Vice Chairman of the Executive Committee. In that latter role, he had responsibilities involving pharmaceuticals, consumer health, technology, global services, and supply chain operations.

Duato became Johnson & Johnson’s CEO in January 2022 and took on the additional role of Chairman in January 2023. Today, he leads a company focused on innovative medicine and MedTech, with a strategy centered on major areas of unmet medical need.

Doug McMillon and Joaquin Duato Have One Major Thing in Common

The most obvious similarity between McMillon and Duato is their extraordinary amount of experience within the companies they ultimately led. Neither executive was an outsider brought in simply to make a quick turnaround.

Doug McMillon and Joaquin Duato spent decades at Walmart and worked across important parts of its business. His career included merchandising, Sam’s Club, international operations, and eventually the overall Walmart organization. That progression gave him a detailed understanding of how the company actually operated.

Duato followed a similarly long internal path at Johnson & Johnson. He joined the company in 1989 and accumulated experience across regions, functions, and business segments before becoming Doug McMillon and Joaquin Duato and Joaquin Duato Johnson & Johnson highlights his nearly 40-year career with the company as a major part of his leadership background.

This kind of internal experience can be extremely valuable. A leader who has spent years inside an organization already understands its culture, strengths, weaknesses, and people. At the same time, internal promotion can create its own challenges because the executive must balance preserving successful traditions with introducing necessary change.

McMillon’s Leadership at Walmart

McMillon’s leadership at Walmart was closely connected with the company’s transition from a traditional retail giant into a more technology-driven, omnichannel business. Customers were increasingly shopping through smartphones, websites, apps, delivery services, and physical stores at the same time.

Rather than treating online retail as something completely separate from physical stores, Walmart increasingly connected its digital and physical operations. That approach made sense because Walmart already possessed an enormous store network that could support pickup, delivery, inventory management, and other services.

Doug McMillon and Joaquin Duato also emphasized investment in Walmart’s workforce. During his tenure, the company increased wages, expanded parental leave, and supported education opportunities for associates. Walmart says its transformation under McMillon centered on becoming a people-led, technology-powered omnichannel retailer.

His leadership was therefore not simply about opening more stores or selling more products. It involved changing how a huge organization responded to digital competition. The challenge was complicated because Walmart had to compete with online-first companies while continuing to operate thousands of physical locations.

Joaquin Duato’s Leadership at Johnson & Johnson

Doug McMillon and Joaquin Duato leadership challenge has been quite different because healthcare is highly regulated, scientifically complex, and deeply dependent on research and innovation. Running a global healthcare organization requires decisions that can affect patients, physicians, researchers, investors, and governments.

Under Duato, Johnson & Johnson has sharpened its focus on innovative medicine and MedTech. The company identifies six high-growth areas of significant unmet medical need: oncology, immunology, neuroscience, cardiovascular care, surgery, and vision.

Technology is another important part of Duato’s leadership philosophy. Johnson & Johnson says he views artificial intelligence as a force multiplier and supports a learning mindset that combines technology with professional expertise.

His background also gives him an international perspective. Duato is a dual citizen of the United States and Spain and has worked across different regions and business functions. That global experience is particularly useful for a healthcare company whose products, research, employees, and customers span international markets.

Doug McMillon vs. Joaquin Duato: Leadership Styles

Comparing the leadership styles of Doug McMillon and Joaquin Duato is interesting because both are experienced operators, but their environments require different priorities. McMillon’s world revolves heavily around customers, prices, stores, logistics, merchandise, employees, and speed.

Duato’s environment involves research, clinical innovation, medical technology, regulation, healthcare professionals, and long development timelines. A retail executive may need to react quickly to changing consumer behavior, while a healthcare leader must often think about scientific progress and patient needs over much longer periods.

McMillon’s background as a merchant appears to have influenced his practical approach to business. He spent time working close to products and customers before eventually reaching the Doug McMillon and Joaquin Duato office. That experience helped him understand the details behind Walmart’s enormous retail machine.

Duato, on the other hand, developed through pharmaceuticals, global operations, technology, and healthcare leadership. His experience positioned him to manage a company where scientific knowledge and business strategy have to work together. Neither approach is necessarily better; they simply reflect the industries each executive has spent decades learning.

How Technology Shaped Both Leaders’ Careers

Technology has become one of the most important connecting themes between Doug McMillon and Joaquin Duato. The industries they lead are completely different, but both have recognized that technology can change how large organizations operate.

At Walmart, technology helped transform shopping. E-commerce, mobile shopping, automated systems, delivery, pickup, data, and digital inventory tools became increasingly important. McMillon’s challenge was to combine these technologies with Walmart’s existing physical infrastructure.

This was not simply an online-versus-store competition. Walmart had to create an experience in which customers could move between digital and physical channels without feeling that they were dealing with completely separate businesses. McMillon’s strategy helped push Walmart toward this broader omnichannel model.

At Johnson & Johnson, technology has a different role. Duato has emphasized data science, intelligent automation, and technology as tools for advancing healthcare. The company has discussed applying these capabilities to areas ranging from innovative medicines to medical technology.

Their Global Experience Is Another Major Similarity

Both executives have extensive international experience, which is increasingly important for leaders of multinational corporations. A company operating around the world cannot rely entirely on a single country’s business model.

McMillon’s international experience came through his leadership of Walmart International before becoming Doug McMillon is no longer Walmart’s CEO. That position required him to understand different markets, customers, regulations, and operational realities. It also gave him experience managing a business spread across numerous countries.

Duato’s international background is equally notable. He began his Johnson & Johnson career in Spain and later held leadership positions across different regions. His work involved pharmaceuticals and other areas of the company’s global operations.

This international exposure matters because global leadership is about more than simply opening offices in different countries. Successful executives need to understand how culture, consumer behavior, regulation, talent, and competition differ from one market to another.

The Biggest Difference Between McMillon and Duato

The biggest difference is obvious: McMillon built his reputation in retail, while Duato built his in healthcare. Walmart sells products directly to consumers, whereas Johnson & Johnson develops healthcare solutions through innovative medicine and MedTech.

Retail tends to operate at a very fast pace. Customers make purchasing decisions quickly, competitors can change prices almost instantly, and companies have to constantly monitor consumer trends. Supply chains also need to be highly responsive.

Healthcare operates differently. Research and development can take years, regulatory requirements are extensive, and scientific evidence plays a central role in decision-making. A healthcare executive must think about innovation while also managing enormous responsibilities related to safety, quality, access, and compliance.

Because of these differences, it would be unfair to judge McMillon and Duato using exactly the same measurements. Their leadership challenges are different. What makes them comparable is not the products their companies sell, but the scale, complexity, and long-term responsibility involved in leading global organizations.

What Their Careers Teach About Successful Leadership

One major lesson from both careers is the value of long-term learning. McMillon did not become Walmart CEO overnight. His progression through different parts of the business gave him a broad perspective before he assumed the top position.

Duato’s career followed the same broad principle. His decades at Johnson & Johnson exposed him to pharmaceuticals, international markets, technology, supply chains, and executive management. By the time he became CEO, he had already spent many years understanding the company from multiple angles.

Another lesson is that modern CEOs cannot afford to ignore technology. McMillon had to respond to the rapid growth of e-commerce and digital shopping. Duato has focused on technologies such as data science and intelligent automation as tools for healthcare innovation.

Perhaps the most important lesson is adaptability. Large companies cannot remain successful simply because they were successful in the past. Leaders must recognize when customers, technology, competitors, or markets are changing and then make difficult decisions about where the organization should go next.

Doug McMillon’s Legacy at Walmart

McMillon’s legacy at Walmart will be closely associated with the company’s digital transformation and its effort to combine technology with its enormous physical retail network. He inherited a company with tremendous scale and helped guide it through a period when traditional retail was being reshaped by digital commerce.

His tenure also placed significant attention on employees. Walmart’s own account of his leadership points to investments in wages, parental leave, and education opportunities alongside technological and e-commerce development.

McMillon’s departure from the Doug McMillon and Joaquin Duato role in January 2026 marked the end of a major chapter in Walmart’s history. After more than three decades with the company, he left behind an organization that had evolved substantially from the retail business he first joined.

His story is especially interesting because it demonstrates how an executive can grow with a company. He started close to the operational side of retail and eventually became responsible for one of the world’s largest corporations.

Joaquin Duato’s Continuing Legacy at Johnson & Johnson

Duato’s leadership story is still being written. Unlike McMillon, who retired as Walmart CEO in 2026, Duato continues to lead Johnson & Johnson as Chairman and Doug McMillon and Joaquin Duato.

His leadership comes during an important period for the company. Johnson & Johnson has been refining its identity around innovative medicine and MedTech, with a strong emphasis on areas where medical needs remain significant.

Duato’s long internal career gives him a detailed understanding of the organization. His experience across pharmaceuticals, consumer health, technology, supply chain, and international markets provides a broad foundation for making decisions at the corporate level.

His continuing challenge will be balancing innovation with execution. Healthcare companies need promising science, but they also need strong operations, talented people, disciplined investment, and the ability to deliver solutions at global scale.

Doug McMillon and Joaquin Duato: Final Comparison

Doug McMillon and Joaquin Duato represent two different versions of modern corporate leadership. McMillon spent decades building his career in retail and eventually led Walmart through a major period of digital and organizational transformation. Duato spent decades in healthcare and rose to the top of Johnson & Johnson after gaining experience across pharmaceuticals, technology, supply chains, and international operations.

Their careers show why experience inside a large organization can be so valuable. Both executives understood their companies from the inside before taking ultimate responsibility for them. That knowledge helped them approach enormous challenges with a perspective that cannot easily be learned from a textbook.

They also demonstrate how technology has become central to virtually every major industry. Walmart needed technology to compete in an increasingly digital retail environment, while Johnson & Johnson is using technology, data, and automation to support healthcare innovation.

Ultimately, the story of Doug McMillon and Joaquin Duato is less about comparing two personalities and more about understanding two leadership journeys. One executive completed a remarkable chapter at Walmart after more than 35 years with the company, while the other continues shaping the future of one of the world’s most prominent healthcare organizations. Their careers offer a useful reminder that effective leadership is rarely about one dramatic decision. It is usually built through years of experience, continuous learning, adaptability, and the ability to guide people through change.
