Last year, Google had an M&M problem. So as it does with most dilemmas, the Internet giant put its data wizards into action.
Employees were eating too much of the free candy and that, the firm surmised, might hinder efforts to keep workers healthy and happy.
So in what could be called Project M&M, a special ops force of behavioral science Ph.D.s conducted surveys of snacking patterns, collected data on the proximity of M&M bins to any given employee, consulted academic papers on food psychology, and launched an experiment.
What if the company kept the chocolates hidden in opaque containers but prominently displayed dried figs, pistachios and other healthful snacks in glass jars? The results: In the New York office alone, employees consumed 3.1 million fewer calories from M&Ms over seven weeks. That's a decrease of nine vending machine-size packages of M&Ms for each of the office's 2,000 employees.
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," Mr. 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.
Some workplace experts question the lengths that Google is going to analyze every corner of its offices.
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.
Google spokeswoman Chrissy Persico said the company does not use such benefits to keep people in the office.
Yet the effects are clear to engineers such as Alex Golynski, who was grabbing a heaping cup of raspberries and espresso from a Lego-inspired micro-kitchen near his cubicle on a recent afternoon.
Mr. Golynski darts around the office in one of the freely available Google scooters. He would have picked fruit over M&Ms even if the candy were easy to reach, he said. And he has never stopped to think much about the nutritional data displayed about the candy.
"The food is convenient," said Mr. Golynski, who has worked on search engineering for five years. "So I spend time at my desk," he added, scooting away.
