How Walmart and Johnson & Johnson Approach Innovation
Innovation looks very different in retail and healthcare. But both companies have made technology and research central to their strategies.
Walmart’s Retail Technology and Digital Growth
Walmart’s innovation focuses on making shopping easier and more convenient. Under McMillon, the company invested in e-commerce, automated supply chains, and digital tools that connect online orders with physical stores. Walmart also began using artificial intelligence to improve search, delivery, and customer service. The goal is to serve customers however they want to shop—in person, online, or both.
Johnson & Johnson’s Healthcare Research and Innovation
Johnson & Johnson’s innovation is built on scientific research. Developing a new medicine or medical device can take years of research, testing, and regulatory review. Under Duato, the company has focused on cancer treatments, immunology, neuroscience, cardiovascular care, surgery, and vision. Johnson & Johnson has also explored how data science and artificial intelligence can support research and operations. In healthcare, innovation must be carefully checked because it can directly affect patient safety.
