The Exploitation Plan for the Horizon Europe project OPUS - Open and Universal Science, outlines a strategic approach to maximise the impact of the project's outcomes, ensuring scientific and practical exploitation of its Key Exploitable Results. What does exploitation mean for the OPUS project? In the context of the OPUS project, "exploitation" refers to the strategic utilisation of the project's outcomes, findings, and results for various purposes beyond the project's initial scope. We are aiming to utilise our results to generate value in the field of open science uptake, specifically concerning how we can reward and encourage open science practices within Research Performing Organizations (RPO) and Research Funding Organizations (RFO). We are striving to develop and test a tangible set of indicators/metrics and initiatives that can be adopted by RPOs and RFOs subsequent to the project. We will advocate for the adoption of Open Science practices by utilising our final deliverable, the Comprehensive Policy Brief for Open Science. This policy brief effectively summarises the project's discoveries and suggestions, concentrating on Open Science principles. As the main outcome of the OPUS project, we will employ a revised Open Science Career Assessment Matrix 2 (OS-CAM2) for researcher assessment.
