“Deliverable 3.2 – Validated key impact pathways for reproducibility, including recommendations” presents a conceptual framework for assessing the relevance and feasibility of reproducibility as a research practice, alongside an evidence synthesis of interventions to strengthen research integrity. Eight co-created pilot activities demonstrate innovative tools and practices, covering planning instruments, reproducible computational workflows, editorial checks, monitoring dashboards, and funder-level promotion strategies. Capacity-building initiatives, including the Reproducibility Hub, training courses, new Reproducibility Networks, and the MERRI meta-research platform, have enhanced skills, awareness, and community infrastructure across Europe. The report also presents a policy roadmap offering actionable recommendations for researchers, publishers, funders, and institutions, emphasising context-sensitive norms, incentives, open practices, and support for research transparency.
