This document discusses how social graphs can transform enterprise applications. It begins with an outline and provides context on the shift from traditional software to social software. A case study on IBM's ThinkPlace collaboration platform is presented, showing how incorporating social graph features like user identities and connections improved idea sharing and discovery. The concepts of social and interest graphs are introduced. Five steps are proposed for transforming enterprise applications, including examining user data and relationships, creating an internal social graph, customizing applications, and integrating social features into existing workflows. Throughout, examples show how social graphs are already used by companies for applications like recommendations, talent management, and business intelligence.
