From strategy+business: An interesting phenomenon emerged in an executive education class I regularly teach. Participants from around the U.S., and sometimes the world, come to the Harvard campus for a week, form teams that work on a significant group project remotely for six months, and then return to Harvard for a concluding session where they present what they’ve accomplished. A couple of years back, one of the teams decided to meet in-person about halfway through. They were so enthusiastic about the meeting, and the project they delivered so impressive, that I have related their experience to subsequent cohorts. Now, more and more teams opt for a mid-project, in-person meeting — a day or two of their own time at their own expense. Those projects continue to be among the best.
