IntelComp underpins the full spectrum of policy processes from agenda-setting to formulation to implementation, monitoring and assessment. The main goal of this work package is to obtain a definition of the Science, Technology and Innovation (STI) ecosystems and model how to implement evidence-based policy modeling for the whole STI process (agenda setting, policy formulation (design), policy Implementation and monitoring and evaluation), to derive functional and technical requirements to the rest of the work packages. The outcomes of this work package will contribute to the definition and implementation of the engagement and cocreation activities under WP6 and WP7 in order to determine the best timing and ways to engage the relevant Public Administrations and stakeholders in the different stages of the process.
