This deliverable, produced under WP2 of the OH‑FINE project, outlines methods to prevent duplication of efforts across ongoing and past projects and networks (Task 2.7). It complements activities in Tasks 5.8, 6.8 and Tasks 10.6–12.6, which focus on collaboration, knowledge exchange and joint initiatives with Horizon Europe projects. The document proposes an initial screening process to identify related ongoing initiatives and a coordination mechanism to facilitate collaboration, ensuring efficient task execution and reducing redundant work among project partners.
