mySociety and OpenUp worked closely with SPOON and the Átlátszónet Foundation, both organisations focus on improving access to government information, to explore a critical but often overlooked question: How do you know if your projects are actually making a difference? In this insightful TICTeC session, SPOON and the Átlátszónet Foundation share their hands-on experiences, practical methodologies, and key findings from their efforts to —for the first time— track and measure the impact of their projects.
