To understand the challenges and opportunities associated with the use of social business, MIT Sloan Management Review, in collaboration with Deloitte, conducted a second annual survey of 2,545 business executives, managers and analysts from organizations around the world. The survey, conducted in the fall of 2012, captured insights from individuals in 99 countries and 25 industries and involved organizations of various sizes. The sample was drawn from a number of sources, including MIT alumni, MIT Sloan Management Review subscribers, Deloitte Dbriefs subscribers and other interested parties. In addition to these survey results, we interviewed 33 business executives and subject matter specialists from a number of industries and disciplines to understand the practical issues facing organizations today. Their insights contributed to a richer understanding of the data. We also drew upon a number of case studies to further illustrate how organizations are leveraging social business.
