These powerful, swirling storms can wipe out navigational aids, air traffic control equipment and radar dishes that ensure the safety of commercial and private aircraft in the U.S. They can also sever communications and keep critical information from flowing between FAA workers on the ground and those based in D.C. and elsewhere. In 2005, hurricanes Katrina and Rita did all this and one thing more: They spurred the FAA to start developing social networking tools to address communication and knowledge management challenges even during extreme circumstances, such as a Category 5 storm.

At the FAA, hurricanes and other disasters raise a fundamental and urgent knowledge management question: Who's available to get things up and running again? "We need to reach our people to find out, Are they OK?" says Hadar, who supports the FAA's disaster recovery efforts. "We also need to know where they are and if they are available to participate in the recovery." Once everyone is accounted for, the agency needs to figure out which disaster recov­ery specialists will do what, and who their counterparts are at other federal, state and local agencies. The specialists themselves have to track their e-mails and instant messages, voice mails, the documents to bring equipment back online and what they spend.

It's a perfect situation for taking social computing tools—such as online social networks and group communications tools like wikis and keyword tagging—and putting them to work as a form of knowledge management.

The Challenge of Knowledge Management

Those dealing with knowledge management (KM) have always faced the challenge of getting information out of people's heads and into a database. Social computing tools seem like a good way to help, since they encourage people to share their knowledge with others, and that expertise can be easily captured.

In fact, social computing represents a third wave for KM: the set of tools and processes companies use to create, track and share intellectual assets, says Patti Anklam, an independent consultant who is focused on KM and social networking. Anklam says the first wave involved digitizing and tracking documents using tools like content management systems. When it became clear that it was too hard to share those documents, companies adopted collaboration tools. With social networks, companies are extending knowledge management to make it easier to connect employees and information.

"A framework for knowledge management consists of understanding what you need to have in place so that people can connect and share with each other, and then...connect to people outside of their own current, small personal networks," Anklam says.
