What can we learn from failures in an evaluation process? This was the theme for the third M&E CoP of 2019. An exploration of ‘what went wrong’ in an evaluation often illuminates possible pitfalls, and gives valuable insights into how to address these. The CoP was structured around the book ‘Evaluation Failures’ (edited by Kylie Hutchinson, Sage Publications 2019). Jennifer Bisgard from Khulisa Management Services is a contributing author, and linked her case study input to some key concepts in M&E. CoP participants then discussed other case studies from the book in groups, using reflective questions to structure their feedback to the bigger CoP.
