The overall objective of this study SMART 2009/0021 is to, as clearly as possible, demonstrate the actual and potential gains for the Information Society in promoting the development and usage of enterprise 2.0. This means that some evidence of the present and the potential future economic impact of enterprise 2.0 should be demonstrated. Best practices on how to implement and use enterprise 2.0 should be provided, with special focus on how enterprise 2.0 can foster innovation and disruptive changes. Furthermore, challenges for a wider deployment of enterprise 2.0, such as limited access to high speed broadband, should be described and followed up by relevant policy recommendations.
