You'd expect employees of Facebook(FB) to be comfortable using social networking as a way to share ideas; what's noteworthy is how ingrained social tools are in the company's inner workings. It uses Facebook Groups -- yes, the same tool the public can use -- but staff use an employee-only or closed version.
Collaboration via Groups has been routine at Facebook for years. Managers use the platform to promote projects for which they hope to generate internal buzz. (At Facebook, buzz can attract top talent to a project.) Employees beta-test products, pose questions, and dole out critiques and "likes." Such immediate feedback lets teams revise and improve their work on the spot, saving wasted effort.
Now Facebook is giving partners a taste of its hypersocial working style. Earlier this year it joined with the website Weather Underground to offer forecasting details inside Facebook Events listings. The companies' primary means of collaboration? Facebook Groups. --Brandon Southward
