This document provides guidance on measuring the business value of social/enterprise social networks. It begins by outlining 6 potential areas where social networks can provide value: safety and sustainability, shareholder value, production/volume and costs, agility, workforce effectiveness, and people engagement. Example use cases and metrics for measuring value are then presented. The document concludes by discussing measuring network maturity and tying metrics to different maturity stages from experimenting to established. The overall message is that social networks can provide business value, and that value should be measured both quantitatively and qualitatively as networks mature.
