grouplet
n.— «When the thing you really want to work on is to make a broad change across the whole organization, you need something new—you need a “grouplet.” These grouplets have practically no budget, and they have no decision-making authority. What they have is a bunch of people who are committed to an idea and willing to work to convince the rest of the company to adopt it.» —“The Google Way: Give Engineers Room” by Bharat Mediratta, Julie Bick New York Times Oct. 21, 2007.
