Their careers are worth exploring because both executives have spent years working toward leadership positions and have helped their companies respond to changing business demands.
Although their professional backgrounds are different, Doug McMillon and Joaquin Duato share an important quality: both understand the challenges of managing a large organization. McMillon’s work has focused on retail, customer experience, and digital shopping, whereas Duato’s responsibilities involve healthcare innovation and medical technology. Looking at their careers side by side offers a useful way to understand how leadership works across different industries.
Who Is Doug McMillon?
Doug McMillon is an American business executive who spent most of his professional life at Walmart. He became the company’s president and chief executive officer in February 2014, but his relationship with Walmart began much earlier. In 1984, he joined the company as an hourly associate. Over the following decades, he worked in different roles and gained experience in areas such as merchandising, operations, and management.
His career is an interesting example of how professional growth can happen over time. McMillon did not begin at the top of the company. Instead, he developed his understanding of Walmart through years of experience before eventually becoming its chief executive. That background gave him a close view of the challenges retailers face, from keeping prices competitive to managing inventory and responding to customers whose shopping habits continue to change.
Doug McMillon’s Time as Walmart CEO
When McMillon became CEO, the retail industry was already changing rapidly. Online shopping was becoming more popular, and customers increasingly expected faster deliveries and easier ways to shop. Walmart had a huge network of physical stores, but it also needed to strengthen its digital business. Under McMillon’s leadership, the company invested in e-commerce, online grocery services, technology, and improvements to its supply chain.
These changes helped Walmart connect its stores with its online shopping services. Customers could use digital platforms to order products and choose convenient ways to collect or receive their purchases. At the same time, Walmart continued competing on price, which has long been central to its business model. Running a company of this size meant balancing new investments with everyday responsibilities, including employee needs, operating expenses, and customer satisfaction.
McMillon’s leadership also involved decisions about the company’s workforce. Walmart employed a large number of people across stores, warehouses, and offices, making employee training and workplace benefits important business considerations. His time as CEO showed that a successful retailer cannot rely on its existing reputation alone. It must keep improving its services and operations as customers, competitors, and technology change.
Why Did Doug McMillon Retire from Walmart?
Doug McMillon retired as Walmart’s president and CEO on January 31, 2026. The company announced in November 2025 that John Furner would succeed him, and the transition took effect on February 1, 2026. Furner had already held senior leadership positions within Walmart, including leading its U.S. business, which gave him substantial experience with the company’s operations and customers.
McMillon’s retirement ended his time as Walmart’s chief executive after nearly 12 years in the role. However, his overall career with the company lasted more than four decades. His journey from hourly associate to CEO remains one of the most notable parts of his professional story. It also makes his career relevant to people interested in leadership, career development, and how large organizations prepare for a change at the top.
Who Is Joaquin Duato?
Joaquin Duato is a business executive best known for his leadership at Johnson & Johnson. He became the company’s chief executive officer in January 2022 and its chairman in January 2023. Before reaching these positions, he spent many years building his career within the healthcare industry, gaining experience in international management, pharmaceutical operations, and business strategy.
Duato’s work involves a different set of challenges from those faced by McMillon. Healthcare companies must consider scientific research, product safety, regulatory requirements, and the needs of patients. Developing a new medicine or medical device can take years and requires considerable investment. Decisions must therefore account for both commercial goals and the responsibility to provide products that meet important healthcare needs.
Joaquin Duato’s Leadership at Johnson & Johnson
As chairman and CEO, Duato helps determine the direction of Johnson & Johnson and oversees its broader business priorities. The company focuses on two main areas: innovative medicines and medical technology. Its work includes treatments for conditions such as cancer and immune disorders, as well as technologies used in surgery, cardiovascular care, and other medical settings.
One of the major responsibilities of healthcare leadership is deciding where to invest for the future. Research projects can take years to produce results, and not every potential treatment becomes an approved product. Companies must also respond to competition, changing regulations, and the cost of developing new technologies. Duato’s role involves balancing these challenges while supporting innovation and maintaining the company’s position in global healthcare markets.
Johnson & Johnson also operates in an environment where public trust matters greatly. Patients and healthcare professionals depend on medical products being safe, reliable, and supported by appropriate evidence. This makes responsible decision-making an important part of the company’s long-term success. Under Duato’s leadership, the organization continues to focus on its pharmaceutical and medical technology businesses.
What Do Doug McMillon and Joaquin Duato Have in Common?
At first glance, retail and healthcare may seem like completely different worlds. However, leading companies in either industry requires many of the same skills. Both McMillon and Duato have experience managing large teams, making major business decisions, and working with people across different countries and markets. They also understand that a company’s long-term success depends on more than short-term financial results.
Another similarity is the need to adapt. McMillon helped Walmart respond to the growth of online shopping and changing customer expectations. Duato works in a healthcare industry where research, technology, and medical needs continue to evolve. Neither company can afford to ignore these developments. Their careers demonstrate why experienced leaders must understand their industries while remaining open to new ideas and better ways of working.
The Main Differences Between the Two Executives

Duato’s professional background is centered on pharmaceuticals, medical technology, and healthcare strategy. Walmart serves customers who purchase everyday products, while Johnson & Johnson develops medicines and medical technologies used by patients and healthcare professionals.
Their current professional situations are different, too. McMillon retired from Walmart’s CEO position in January 2026, and John Furner took over the role the following day. Duato, meanwhile, continues to serve as chairman and CEO of Johnson & Johnson. Comparing the two requires recognizing that McMillon’s story is now largely about his leadership legacy, while Duato remains responsible for guiding his company’s current strategy.
