In 1992, Satya Nadella joined Microsoft, and by 2014, he became CEO. As he toured Microsoft offices worldwide that year, he discovered a culture of division—teams hoped others would fail to make their own divisions look better. Collaboration was minimal, and communication was lacking. Believing culture was key to Microsoft’s growth, Nadella embraced the essence of Carol Dweck’s Mindset, introducing a cultural shift: Let’s not be know-it-alls. Let’s be learn-it-alls.
