Linda Morra Imas

Linda was Secretary of the IDEAS Board from 2009 to 2015. She has been active in IDEAS on many fronts: supporting the development of competencies for evaluators, leading the work on qualification and/or credentialing and supporting the development of ethics guidelines for evaluation. This work led to the Board inviting her to become an external advisor on professionalization issues, on which she continues to be active.
She was also instrumental in setting up the Thematic Interest Groups in IDEAS and developed the Guidelines for these Groups.
Her service to the international development evaluation community has been exemplary and her contributions to IDEAS have been praiseworthy and will stand the test of time.
Dr. Morra Imas is one of the creators and co-directors of IPDET and has more than 30 years of experience with private and public sector evaluation and training in M&E throughout the world. With Ray C. Rist, she co-authored the comprehensive text, “The Road to Results: Designing and Conducting Effective Development Evaluations” (World Bank, 2009) which has since been translated into several languages. Retired as Chief Evaluation Officer and Advisor, Evaluation Capacity Development of the Independent Evaluation Group, World Bank Group, Dr. Morra Imas consults and trains on monitoring and evaluation for organizations and national governments. She is former Director of Education and Employment Program Evaluation for the U.S. Government Accountability Office and has taught program evaluation at George Washington University as an adjunct professor.

Chen Zhaoying

Professor Chen was instrumental in organizing, in September 8th, 2002, in Beijing, China, the first Assembly of IDEAS, when a Constituent Assembly launched IDEAS, elected a widely representative Board, approved a three-year work plan and budget. She can thus be considered the “mother” of IDEAS, the same way she is known, in China, as the “mother of evaluation” in the country. She was a member of the first elected Board.
Her promotion of evaluation culture and her support for young evaluators and new approaches has been exemplary. She has played a key role in connecting the emerging evaluation culture in China to the world. She has pioneered program evaluations in China and has introduced international standards for evaluation in Chinese practice. Since 1995 Professor Chen has worked for the National Centre for Science and Technology Evaluation (NCSTE) in Beijing, China. She built up NCSTE as a special consultancy arm of the Ministry of Science and Technology as Executive Director General up to 2004.
She has drafted the Chinese science and technology evaluation standards and has published numerous evaluation reports. She has designed, implemented and managed complex and strategic evaluations, including a Chinese evaluation of the support that China received from the multilateral development banks. In 2010 Professor Chen retired from NCSTE management and became a high level advisor.


Ray Rist

Dr. Rist was President of IDEAS for many mandates, and has been instrumental in developing IDEAS Biennial Conferences and Global Assemblies, that have gained in traction and intellectual depth from Johannesburg (2009) to Amman (2011) to Barbados (2013). He has turned each Assembly into a highly influential and recognized publication, made available here in our Public Library.
He is one of the creators and co-directors of IPDET, and has enthusiastically given incentives for IPDET alumini and evaluators to join IDEAS. Retired from the Independent Evaluation Group of the World Bank, Dr. Rist continues to advise organizations and national governments throughout the world on how to design and build results-based M&E systems. His career includes 15 years in the U.S. Government with senior appointments in both the executive and legislative branches. He has held professorships at Johns Hopkins, Cornell, and George Washington Universities and been a Fulbright Fellow at the Max Planck Institute.
He has authored or edited 32 books, many of which are available for download in our Public Library. He wrote more than 140 articles, and lectured in more than 85 countries.

Bob Picciotto

Robert (Bob) Picciotto became internationally prominent in evaluation when he was appointed as Director-General Evaluation of the World Bank Group in 1992 – a post he occupied for two five year terms until 2002. In this position he was instrumental in ensuring the birth of IDEAS and provided highly effective support for the organization in its first years. After retiring from the World Bank Group Bob has provided senior independent evaluation advice to many multilateral development banks, the United Nations, to several bilateral donors and to the Rockefeller Foundation. Until his recent move to New Zealand he was a trustee of the International Association for Digital Publications and served on the advisory council of Wilton Park, as well as the Boards of the United Kingdom Evaluation Society and the European Evaluation Society. Up to 2015 he taught evaluation as a Visiting Professor at the International Development Institute of King’s College London.
Bob Picciotto was appointed honorary member of IDEAS by its first Board, in recognition of the strategic advice he provided to the Board and thus to IDEAS. His status as honorary member has been more than amplified by the exemplary role he has played in the international evaluation community since his retirement from the World Bank Group.
