The document details the 'Big Policy Canvas' project, a 24-month initiative aimed at transforming public sector policy-making through data-driven approaches funded by the EU. It emphasizes the importance of big data, open data, and co-creation with citizens to develop effective, evidence-based policies, and outlines the workshop structure designed to foster discussions on these themes. The project seeks to create a knowledge base, methodologies, and frameworks for mapping public sector needs and research challenges in order to enhance policy innovation and stakeholder engagement.
