“While 72 percent of companies use social technologies in some way, very few are anywhere near to achieving the full potential benefit. In fact, the most powerful applications of social technologies in the global economy are largely untapped. Companies will go on developing ways to reach consumers through social technologies and gathering insights for product development, marketing, and customer service. Yet the McKinsey Global Institute (MGI) finds that twice as much potential value lies in using social tools to enhance communications, knowledge sharing, and collaboration within and across enterprises. MGI’s estimates suggest that by fully implementing social technologies, companies have an opportunity to raise the productivity of interaction workers—high-skill knowledge workers, including managers and professionals—by 20 to 25 percent.”
