A McKinsey report (PDF here) entitled "Building the Web 2.0 Enterprise" says companies are picking up the pace in terms of adopting 2.0 tools for a variety of uses, but dissatisfaction with existing tools is high. Just 21% of companies surveyed said they were satisfied, 22% are dissatisfied, and some have stopped using particular tools altogether.

Among companies that like the tools, though, changes are running deep, including new approaches to "management practices and organizational structures. Some are taking steps to open their corporate 'ecosystems' by encouraging customers to join them in developing products and by using new tools to tap distributed knowledge."

Another survey, by research and consulting firm Summus Limited, reports that just under half of companies responding say they use Web 2.0 tools. "Why hasn't business adopted them more fully? It would appear that marketers of Web 2.0 platforms and services haven't done as good a job as they might of explaining what they have to offer," says Summus president Eva Schmatz.
