Conceptual framework

The knowledge production modes (KPM) framework was developed to evaluate the relevance and feasibility of reproducibility as a research practice and a criterion of research quality in diverse settings. Relevance is shaped by a community’s epistemology, methodological standards, and any proprietary or commercial constraints. Feasibility depends on the subject matter, available resources, the type of reproducibility pursued, and the level of uncertainty associated with theoretical and methodological conditions.

Evidence synthesis

Findings from a few publications indicate that reproducibility is hindered by the absence of data and code, inadequate documentation, unstable computational setups, and, in qualitative research, a mismatch with standard expectations for reproducibility. They also identify drivers such as growing awareness of reproducibility issues, increasing use of open science standards, and strong documentation and ethical data practices. Together, these insights support the need for a threaded publication model that links methods, data, code, and contextual materials to address these barriers.

Innovative tools & practices

To gain a deeper understanding of the causes, consequences, and potential solutions for perceived low reproducibility in research across different contexts, TIER2 focused on the social, life, and computer sciences, as well as research publishers and funders. The project aimed to raise awareness, build capacity, and propose innovative solutions tailored to diverse research cultures. Central to this effort were eight pilot activities designed to develop, implement, and evaluate new reproducibility-related tools and practices, with a strong emphasis on stakeholder engagement and collaboration throughout the project.

Policy roadmap

The stakeholder roadmap outlines priorities for improving research reproducibility. It includes practical policy recommendations, guidelines, and briefs for funders, institutions, policymakers, administrators, integrity officers, publishers, and researchers in Europe and beyond. The policy briefs focus on promoting reproducibility-sensitive policymaking that accounts for epistemic diversity across research fields, as well as highlighting the need for stronger incentives, open practices, and dedicated support to enhance the transparency and trustworthiness of AI research.
