The titan of Internet data is taking its own medicine, using the data analysis that has helped the company produce $55 billion in revenue each year to improve the morale and productivity of its 40,000 employees. Many tech companies offer perks such as free snacks or cafeteria food. But at Google, almost every benefit is broken down into crunchable, poll-able or graphicable data, including salaries, the length of maternity leave, the size of the plates used at the food bar or even the squishy goal of workplace happiness.
Google says it's too hard to prove that the M&M experiment directly led to a svelter staff or whether employees felt happier just because they were eating less of the calorie-packed snack. It won't talk about how many people leave the company each year.
But the Mountain View, Calif., firm often ranks high on best places to work surveys by Fortune magazine and other business publications. And the company credits efforts like the M&M project as a testament to the benefits of science over feel-good ideas or gut instinct that have dominated human resource philosophy.
"Data can be a way at getting to the truth. When people talk about data, it becomes an abstract of machines, robots and terabytes of information. But really, it's just facts; numbers that describe a reality," said Laszlo Bock, senior vice president of People Operations, the group overseeing most human resource issues.
Of course, the use of data doesn't negate a manager's instinct or common sense, he said. In August of last year, Google started giving death benefits because it was "the right thing to do," Bock said — a decision that was not based on an in-depth data analysis. The benefit grants the partners of deceased employees half of that person's pay for a full decade.
But too often, Bock said, leaders at other firms rely on what feels right without considering the truths that can be laid bare in the collection of data.
Some workplace experts question the lengths that Google is going to analyze every corner of its offices. Some of the lab experiments are remarkably obvious. If you put out more free fruit, of course it will be taken.
And some analysts question whether the free meals, napping stations and inexpensive massages make people stay in the office longer, perpetuating a work-obsessed culture that has eaten into family life and community.
"You have to question the expectations behind such perks. If they are giving you dinner and lunch, you are probably not expected to leave at that time. Perks aren't just about fun and games," said Miriam Salpeter, owner of Keppie Careers, a job search and social media consulting firm. "They may have really good motives, but for a for-profit business, the motives are ultimately to make a profit, and everyone is a cog in that wheel for creating the good ideas, useful tools and other things the company is creating."
Yet other experts say Google is trying to signal that it cares about employees. And in a dour economy where pensions, health care and other core benefits are being cut to the bone, Google's efforts are welcomed by new employees.
"There may be a symbolic importance in the M&Ms, where an employee could interpret the experiment as part of a culture that cares for them, where leaders are connected to its people," said John Nelson, a career expert and author of "What Color is My Parachute for Retirement."
For Google, it's more than just the candy that employees consume. In another case, the company tried to get workers to drink more water. So it stashed bottled water on eye-level shelves and behind clear glass. It then put sugary sodas on the bottom shelves of refrigerators and behind frosted glass. After several weeks, water consumption increased 47 percent while the calories consumed by drinking sugary beverages fell 7 percent.
Some of these results were displayed on signs in hallways and in the cafeterias for Google's stats-loving employees. In a follow-up survey, Google said 70 percent of its 40,000 workforce said they like knowing nutritional facts.
In the New York office alone, there are four full cafeterias and 35 "microkitchens." Co-founder Sergey Brin insists that every Google employee be no more than 200 feet away from free food. The idea is that eating brings people together, and new products and services could be imagined when engineers and business leaders meet at kitchens and dining halls.
