In 2014, when Satya Nadella became Microsoft CEO, the company struggled to keep up with a rapidly changing technology sector. He transformed the company's culture with three words: “learn-it-all”, not “know-it-all.” Nadella sought to change how employees approached learning, collaboration and innovation at the technology giant. Drawing on psychologist Carol Dweck's research on growth mindset, he encouraged employees to embrace curiosity, acknowledge what they didn't know, and continuously improve their skills. The shift moved the focus away from proving existing expertise towards learning from others and adapting to change. Nadella repeatedly used the phrase and incorporated the philosophy into management evaluations, making curiosity an important part of Microsoft's workplace culture. More than a decade later, he continues to emphasise learning as the company navigates changes driven by artificial intelligence, while maintaining that its future depends on adapting to new technologies and customer needs.
When Nadella became CEO, Microsoft struggled to regain traction in an industry increasingly defined by cloud computing and new technology platforms. He thought a culture that already knew the answers could kill experimentation and inhibit employees from adapting to changing circumstances. The “learn-it-all” approach encouraged employees to ask questions, share knowledge and treat mistakes as opportunities to improve. Rather than viewing uncertainty as a weakness, employees were encouraged to approach unfamiliar problems with curiosity. The philosophy drew on Carol Dweck's growth-mindset research, which distinguishes between believing abilities are fixed and viewing them as qualities that can develop through effort and learning.
In a recent communication to employees, Nadella reiterated the importance of growth mindset as Microsoft enters another phase of technological change. "Growth mindset has served us well over the last decade—the everyday practice of being a learn-it-all, not a know-it-all," he wrote. "It has reshaped our culture and helped us lead with greater humility and empathy. We need to keep that." He also admitted transformation can bring uncertainty, especially as teams restructure and responsibilities move around. His message came as Microsoft cut jobs even as it continued to pour money into infrastructure and artificial intelligence. Nadella described the company's next phase as a process of “unlearning” and “learning,” requiring employees to maintain existing businesses while developing new products, categories and business models.
Nadella has outlined three business priorities for Microsoft: security, quality and AI transformation. He said the company must continue strengthening its existing products while rethinking its technology infrastructure, platforms and applications for AI workloads. He also described a broader shift in Microsoft's mission, from building software for specific tasks to creating tools that let people and organisations develop their own solutions. The approach reflects Microsoft's efforts to integrate AI across its products and services while building the computing infrastructure required to support them.
Nadella’s focus on learning reflects his view that a company’s long-term relevance depends on its ability to change, not just on what it has already done. In his message to employees, he wrote, "What we’ve learned over the past five decades is that success is not about longevity. It’s about relevance. Our future won’t be defined by what we’ve built before, but by what we empower others to build now." The principle that helped reshape Microsoft's workplace culture remains central to how Nadella wants the company to respond to AI. As technology changes how people work and build products, the “learn-it-all” mindset remains a framework for encouraging employees to learn, experiment, and adapt.
