The Data Ethics Decision Aid (DEDA) helps data analysts, project managers, and policymakers work together to identify both ethical and practical issues in data and AI projects.
Since 2018, the DEDA toolkit has helped organizations identify issues and areas of concern, document the deliberation process, and promote accountability to various stakeholders and the public.
“During the session, people began to feel more responsible and engaged. They also gained greater insight into each other’s perspectives.”
Ingrid Hazelhoff, data ethics advisor at Wetterskip Fryslân
DEDA consists of a poster and a manual. All tools are published as Open Access by the Data School at Utrecht University.
DEDA was thoroughly revised in 2026 in light of recent technological, legal, and geopolitical developments. Although the old materials can still be used, we recommend the latest materials, especially for projects involving generative AI.
