SAS2 Social Analysis Systems offers a new approach to creating and using knowledge for the common good. Its purpose is to broaden and deepen the range of concepts, tools and transferable skills to support dialogue and democratic engagement in the sphere of knowledge. The materials presented in the Guide support a shift towards flexibly-structured processes to engage people in inquiry sustained by experience, adapted to context and responsive to important needs.This approach bridges the gap between conventional inquiry based on 'hard evidence' and participatory methods that emphasize 'building consensus' at any cost. The book presents: original and transferable skills for collaborative inquiry and social engagement; grounded and theoretically informed conceptual foundations integrating perspectives from many disciplines and theoretical orientations; clear writing and mapping of information in a straight forward guide; and, authentic examples of the application of techniques in developing country contexts.
