No surprises really, but McKinsey is waving the data carrot. In their own words;
A new class of company is emerging—one that uses collaborative Web 2.0 technologies intensively to connect the internal efforts of employees and to extend the organization’s reach to customers, partners, and suppliers. We call this new kind of company the networked enterprise. Results from our analysis of proprietary survey data show that the Web 2.0 use of these companies is significantly improving their reported performance. In fact, our data show that fully networked enterprises are not only more likely to be market leaders or to be gaining market share but also use management practices that lead to margins higher than those of companies using the Web in more limited ways.
