RIS3 WORKBOOK FOR PROJECTS provides practical guidance for designing regional development projects that meet the requirements of the EU's 2014-2020 programme period by focusing on smart specialization. It summarizes insights from workshops held with hundreds of participants on topics like identifying societal needs, co-creating solutions with stakeholders, and ensuring projects have impact beyond just funding periods. The workbook is intended to help project managers, researchers, and regional organizations plan projects that align with their region's smart specialization strategy and produce meaningful outcomes.
