In recent years, using technology to change the way people work has often meant painful disruption, as CIOs rolled enterprise software programs through the ranks of reluctant staffers. Today, employees are more likely to bring in new technologies on their own—and to do so enthusiastically—through their Web browser, whether it’s starting a blog, setting up a wiki to share knowledge, or collaborating on documents hosted online.

Andrew McAfee, principal research scientist at the Center for Digital Business at the MIT Sloan School of Management, has been watching this shift closely. His new book, Enterprise 2.0: New Collaborative Tools for your Organization’s Toughest Challenges, explores the ways that leading organizations are bringing Web 2.0 tools inside. McAfee calls these tools “emergent social software platforms”—highly visible environments with tools that evolve as people use them—and he is optimistic about their potential to improve the way we work.
