There is incontrovertible wisdom in learning from failure, yet organisations that do it well are extraordinarily rare. In this series, launched as a key feature of the Impact/Failure conclave, we feature articles, podcasts, and videos by social sector leaders and development professionals, where they share the challenges they faced, reflect upon their mistakes, and highlight the lessons learned in light of their failures. Through these experiences, we learn to fail forward, fail more productively, and fail better. These stories are crowd-sourced and we invite you to share your failure story so that we may celebrate the learning!
