Ethan Bernstein, associate professor in the organizational behavior unit at the Harvard Business School, talks to us about how he and his peers are assessing the open office phenomenon.

Referencing the dream of an open, egalitarian workspace going back to the 1940s, he discusses the elements involved in establishing a true rhythm of collaboration and predicts three key themes for the future.
