Realistic Evaluation shows how program evaluation needs to be, and can be bettered. It presents a profound yet highly readable critique of current evaluation practice, and goes on to introduce a `manifesto'' and `handbook'' for a fresh approach.
The main body of this book is devoted to the articulation of a new evaluation paradigm, which promises greater validity and utility from the findings of evaluation studies. The authors call this new approach `realistic evaluation''. The name reflects the paradigm''s foundation in scientific realist philosophy, its commitment to the idea that programmes deal with real problems rather than mere social constructions, and its primary intention, which is to inform realistic developments in policy making that benefit programme participants and the public. Ray Pawson and Nicholas Tilley argue with passion that scientific evaluation requires a careful blend of theory and method, quality and quantity, ambition and realism.
