The document introduces the Social Disruption Index (SDI), a new metric being developed by W2O Group and The Social Starts Fund to measure the level of disruption across different industries based on factors like start-ups, investment, and changing consumer behavior. The SDI will analyze industries to determine their "disruption stage" on a scale from pre-disruptive to post-disruptive. It will also consider legal/regulatory factors that may accelerate or stall disruption. An initial release is planned for June 2015 with further quarterly analyses. The goal is to help identify innovative concepts and disrupted markets at an early stage.
