Expert Facilitators lead and guide co-creation processes among stakeholders, enhancing creativity and mutual understanding and ensuring effective outcomes. To excel in their work, facilitators need a diverse set of skills, incl. technical expertise and soft skills like conflict resolution and active listening. Keeping up with the latest co-creation trends/practices (incl. the incorporation of SSH aspects) can be challenging. Although there are many initiatives offering resources to upgrade co-creation skills, they are frequently fragmented and scattered through hundreds of platforms and websites. EU·FFICIENT will create a dedicated platform and methodology to provide facilitators with personalized access to best-in-class co-creation resources, as well as training and networking opportunities. The platform will allow users to self-assess their training needs in co-creation before they access a Customised Training Program comprising easy-to-digest audio-visual material, online and f2f events. Upon completion of the training modules, Expert Facilitators will receive a "Certification of Completion" aligned with EC's vision for lifelong learning and micro-credentials. The project will pilot four Communities of Expert Facilitators (CEFs): Advanced Manufacturing, HealthTech, Mobility, and AI/Digital, facilitating cross-fertilization and cross-comparison. EU·FFICIENT targets over 2,000 facilitators through the four CEFs, with at least 500 actively participating in training – an activity coordinated by UIIN network, the EU leader in university-industry training. The partnership brings representatives from academia (incl. 6 HEIs), industry and the public sector, as well as dedicated experts on co-creation, training, community building, online platform development and policy briefing. The highly complementary consortium is formed by partners from many different backgrounds and geographies (incl. Widening and Associated countries), enabling an agile kick-start of the piloting.
