Social enterprise has become a much discussed term in recent years, often in conjunction with the public sector - the idea that entrepreneurship might somehow step in and save the public purse has taken hold in a number of areas. This book introduces and explains the terminology surrounding social enterprise and brings much-needed rigour to proceedings by demonstrating how this can be measured, evaluated and held accountable. A range of validated evaluation measures, tools and techniques, such as 'SROI', the 'Outcomes Star' and randomised control trials, are presented in individual research projects, conducted by an exciting and eclectic mix of international authors who are recognised experts in the field of social enterprise. Wrapping up with the ground-breaking use of a General Self-Efficacy scale, a reflective critique of social finance and a challenge to the actual concept of social enterprise, the book discusses the potential disadvantages that can arise from the commodification of social enterprise activities, resulting in a fascinating summary of current thinking surrounding this topic.
