Are you a grant maker, manager or evaluator who must assess your work to improve as well as be accountable for the use of resources and results? Does the project, program or organization you fund, manage or evaluate contend with substantial uncertainty about what to do and what will be the results? Do you thus experience constant change and unexpected and unforeseeable actors and factors in your intervention? Do you need to know what you are achieving and how in real time? And therefore, do you seek an alternative to conventional monitoring and evaluation of social change results? If yes, then you are the audience for this book.Beginning in 2002, working closely with co-evaluators and commissioners of evaluations, the author developed Outcome Harvesting to enable evaluators, grant makers, and managers to identify, formulate, verify, and make sense of changes that interventions have influenced in a broad range of cutting-edge innovation and development projects and programs around the world. Over these years, he led Outcome Harvesting evaluative exercises involving almost 500 non-governmental organizations, networks, government agencies, funding agencies, community-based organizations, research institutes and university programs. In over fifty evaluations, with forty co-evaluators he has harvested thousands of outcomes on six continents.Outcome Harvesting has proven useful in evaluations of a great diversity of initiatives: human rights advocacy, political, economic and environmental advocacy, arts and culture, health systems, information and communication technology, conflict and peace, water and sanitation, taxonomy for development, violence against women, rural development, organic agriculture, participatory democracy, waste management, public sector reform, good governance, eLearning, social accountability, and business competition, amongst others.In this book, the author explains the steps of Outcome Harvesting and how to customize them according to the nine underlying principles. He shares his experience and gives practical advice on how to work with Outcome Harvesting and remain true to its essential features.
