SuccessFactors promotes its set of business software modules as a "Business Execution Suite." Last year, the company acquired the social business and collaboration software company CubeTree and integrated their product into its business suite. CubeTree creates a platform for social networking within an enterprise, enabling a news feed, blogs, wikis, polls, and other activities. For HR purposes, that can speed up the recruiting process by giving stakeholders an easy way to review resume and share their comments and opinions on candidates. Among the companies adopting CubeTree is publishing house Houghton Mifflin Harcourt, where employees use the software to find subject matter experts and share best practices. "SuccessFactors' CubeTree has rapidly established itself inside our enterprise," says CIO Paul Wilcox. "Employees tell me it's easier to find and connect with colleagues and gain insight into cross-functional activities. It's a wonderfully powerful tool."
