Collaboration and communication are tricky to quantify (how do you know if your employees are talking more over Gchat/conversations in the office or from home?). But productivity isn’t so hard to measure. It’s work over time. And some studies have shown that working from home can make certain workers more productive.

The most commonly cited study in the field of home-work and productivity comes from Stanford. The results were clear: Telecommuting is nothing to be afraid of. Workers at a Chinese travel agency took fewer breaks and sick-days, answered more calls every minute, and reported improved work satisfaction when they worked from home. Later, the agency allowed the employees in the experiment to choose if they wanted to work from home, and productivity increased by 22%.
