Enterprise social software, also known as Enterprise 2.0, is a term describing social software used in "enterprise" (business) contexts. It includes social and networked modifications to company intranets and other classic software platforms used by large companies to organize their communication. In contrast to traditional enterprise software, which imposes structure prior to use, this generation of software tends to encourage use prior to providing structure.
The association AIIMdefines Enterprise 2.0 as a system of web-based technologies that provide rapid and agile collaboration, information sharing, emergence and integration capabilities in the extended enterprise.
