This document discusses achieving content governance across collaborative and social business platforms. It begins by introducing content governance and the challenges of governing multiple target repositories, including traditional ECM, email, file shares, SharePoint, cloud ECM, and cloud file sharing. It then discusses different governance approaches like repository-based, content type-based, and lifecycle-based governance. It proposes a hybrid lifecycle model and "policy hub service" to help achieve governance across platforms in both on-premise and cloud environments. It concludes by questioning whether unified governance of SharePoint, email, and file shares provides full governance and how to best approach hybrid governance.
