Humanize this paragraph : When Satya Nadella assumed the role of Chief Executive Officer at Microsoft in February 2014, the technology giant was caught in a cycle of cultural stagnation and fierce internal rivalry. Marked by a toxic stack-ranking performance review system and rigid departmental silos, employees were heavily incentivized to guard their personal territories rather than share knowledge or collaborate across teams. Addressing this required executing Kotter’s third step of change management: developing a compelling vision and strategy. Nadella initiated this by anchoring Microsoft’s identity in Carol Dweck’s concept of a "growth mindset," pivoting the corporate narrative from a defensive "know-it-all" posture to an adaptive "learn-it-all" ethos. This cultural philosophy was seamlessly integrated with Microsoft’s business strategy, establishing the defining corporate mission to empower every person and organization on the planet to achieve more while executing a decisive strategic pivot toward mobile-first, cloud-first operations centered on Azure and open-source integration.
