This call for tenders concerns the provision of firm-level case studies on the use of artificial intelligence (AI) technologies across selected EU Member States. The project will generate qualitative evidence on how firms adopt and deploy AI in practice and how this affects productivity, work organisation, skills, and employment conditions. The study will cover different types of AI technologies and sectors, and will contribute to Eurofound’s broader research on AI, labour markets, and productivity, supporting policy analysis and the design of a subsequent EU-level company survey.
