What methodological tools have been most useful in doing evaluations? What are some of the new methodologies that are being used and developed? Will the type of things evaluated expand from programmes, personnel and products to foreign aid, medical technology, environmental interventions and World Bank loan programmes? What will evaluation be like in the 21st century? An impressive group of renowned evaluators explore these questions to explain how evaluation has come to be what it is today, and to explore what the likely outcomes are for evaluation in the future. Topics discussed include: what makes evaluation different from other disciplines; the links and differences between the evaluation and the auditing professions; which activities have priority in evaluation; new methodological approaches to doing evaluation; the issues of advocacy versus truth in evaluation; and evaluating programmes versus empowering people to evaluate their own programmes.
