Early in his life, William McNabb, the former CEO of Vanguard, recounted an insight he had about the power of teamwork — and teamwork done right. Growing up, he had a newspaper route with a friend. Their typical approach to this joint venture was to “divide and conquer” — to split the route and each complete half of it individually. It took them each 35 minutes to complete their half of the route when they worked together in this way. This approach probably sounds reasonable, and unsurprisingly so – the divide-and-conquer approach to teamwork reflects both the dominant approach to teamwork in many U.S. organizations and the broader culture of individualism in the United States.
