The McKinsey Quarterly does a write-up of its annual survey on social technologies in the enterprise work environment. Over 70 percent of the companies McKinsey surveyed used at least one of the following: social networking, blogs, microblogging or video sharing. But they reported that benefits like faster info access, lower-cost communications and faster access to expertise, though definitely there to be had, were sometimes difficult to maintain at scale. The study’s worth a download, though someone should introduce McKinsey to Tufte and other principles of data visualization. We’re finishing up some GigaOM Pro analysis on these themes, especially in the context of consumerized tools. And don’t forget our Net:Work event on the future of work is this week. Pro members can still get a discount.
