People analytics is a data-driven understanding of HR practices, programs, and processes. When faced with tough HR challenges like uncovering why high performers are leaving or deciding who should lead a new initiative, the traditional response is to engage in endless discussions based on gut feelings, intuition, or anecdotes. However, at Google, we use people analytics as the foundation for recruiting, developing, and retaining employees. We've discovered that data-informed decisions lead to more effective and fair solutions.
