Can’t resist checking your smartphone or mobile device? Sure, all this connectivity keeps you in touch with your team and the office—but at what cost?

In Sleeping with Your Smartphone, Harvard Business School professor Leslie Perlow reveals how you can disconnect and become more productive in the process. In fact, she shows that you can devote more time to your personal life and accomplish more at work.

The good news is that this doesn’t require a grand organizational makeover or buy-in from the CEO. All it takes is collaboration between you and your team—working together and making small, doable changes.

What started as an experiment with a six-person team at The Boston Consulting Group—one of the world’s elite management consulting firms—triggered a global initiative that eventually spanned more than nine hundred BCG teams in thirty countries across five continents.
