In early 2009 at Google, "statisticians . . . embarked on a plan code-named Project Oxygen. The 'people analytics' teams at the company produced what might be called the Eight Habits of Highly Effective Google Managers. 'My first reaction was, that’s it?' says Laszlo Bock, Google’s vice president . . . for human resources. 'The starting point was that our best managers have teams that perform better, are retained better, are happier — they do everything better,' Mr. Bock says. 'So the biggest controllable factor that we could see was the quality of the manager, and how they sort of made things happen. The question we then asked was: What if every manager was that good? And then you start saying: Well, what makes them that good? And how do you do it?' He tells the story of one manager whose employees seemed to despise him. He was driving them too hard. They found him bossy, arrogant, political, secretive. They wanted to quit his team. 'He’s brilliant, but he did everything wrong when it came to leading a team,' Mr. Bock recalls. Because of that heavy hand, this manager was denied a promotion he wanted, and was told that his style was the reason. But Google gave him one-on-one coaching — the company has coaches on staff, rather than hiring from the outside. Six months later, team members were grudgingly acknowledging in surveys that the manager had improved." (1)
