In recent years, social impact assessment (SIA) has become an important issue for organizations in the social and solidarity economy (SSE). SIA refers to the measurement of the effects of these organizations on society, and it is increasingly seen as a performance measurement for this type of organization.

Social Impact in Solidarity-based Organizations is based on a series of original case studies of SIA approaches carried out in a variety of organizations. It takes a nuanced, reflective look at SIA, charting a path between unreserved promotion and wholesale rejection of the very principle of the approach. The book focuses on the debates, uses and limits of SIA practices, placing them in their own contexts, values, challenges and objectives.
