Project Overview

"Project Oxygen - Their mission was to build better bosses.

So, as only a data-mining giant like Google can do, it began analyzing performance reviews, feedback surveys and nominations for top-manager awards. They correlated phrases, words, praise and complaints.

Later that year, the “people analytics” teams at the company produced what might be called the Eight Habits of Highly Effective Google Managers.

Talent management is critical to how Google creates value: through technological innovation. Google’s use of data to recruit and develop employees has proved its effectiveness; training programs based on Project Oxygen, for instance, achieved a statistically significant improvement in manager quality for 75% of underperforming managers (7). Strong talent management also helps Google capture value through cost savings. Attrition is costly to Google, not only because they must recruit, but also because ex-Googlers accumulate valuable organizational knowledge. Analytics help Google reduce attrition in cost-effective ways; the decision to extend maternity leave reduced new mother attrition rates by 50% and “was much better” for Google’s bottom line (9). Google also uses algorithms to predict which employees may quit, which allows for an intervention that may retain the employee (10)."
