The B1MG stakeholder coordination portal aims to efficiently deliver timely analysis of challenges, opportunities and solutions resulting from external stakeholders to the operational WPs. Developed by WP1 in close relationship with the communication and coordination teams (WP6), it delivers tools and defines workflows to de-risk and improve the flow of data generation and integration towards patients. These tools will help reduce cross-border barriers, and facilitate the development of operational pipelines based on the integration of genomic and health data. The stakeholder portal allows the users to share contact information and develop a network within the B1MG project. People are organised in groups that reflect the stakeholder clusters with the possibility of users to create transversal sub-communities. The portal functionalities facilitate community participation and engagement, communication and collaboration and documents sharing and management. This allows the creation of a vibrant community, organised and focused, that can collaborate in an effective and advantageous way for improving the project outcomes.
