On April 2, members of The Durability Collective convened a panel discussion at the Marmalade Festival.
Entitled “Does the Change Last?: Making mid- and long-term impact measurement affordable and feasible”, The Durability Collective panel discussion was held at The Story Museum, with a packed room of highly engaged funders, practitioners, and other social impact experts, resulting in a rich discussion.
Moderated by Stephan Chambers, Director of The Marshall Institute for Philanthropy and Social Entrepreneurship at LSE, the panel included Generation Global CEO Mona Mourshed, Deputy CEO of UBS Optimus Foundation Nalini Tarakeshwar, CEO of Last Mile Health Lisha McCormick, and Director of Impact Frontiers Matt Ripley.
This group shared perspectives and experiences from their own work around affordable, doable measurement approaches, challenging the conventional wisdom that medium and long-term outcomes measurement is too hard or expensive to undertake. Members discussed roadblocks they’ve encountered in implementing impact measurement, how they’ve overcome them, and where they’ve found success in tracking and sharing outcomes over time.
Participants were invited to join The Durability Collective’s new learning community that seeks to advance the movement towards sustainable impact measurement.
The annual Marmalade Festival, focuses on systems change through the lens of people, power, and place. It is produced in partnership with the Skoll World Forum, and this year from April 1-4 brought together nearly 4,000 people for 68 inspiring events across 10 Oxford venues.
