One of Bezos’s more memorable behind-the-scenes moments came during an off-site retreat, says Risher. “People were saying that groups needed to communicate more. Jeff got up and said, ‘No, communication is terrible!’ ” The pronouncement shocked his managers. But Bezos pursued his idea of a decentralized, disentangled company where small groups can innovate and test their visions independently of everyone else. He came up with the notion of the “two-pizza team”: If you can’t feed a team with two pizzas, it’s too large. That limits a task force to five to seven people, depending on their appetites.
