This deliverable (D8.2) presents the Quality Control Plan (QCP) for the SINGLE project, outlining the procedures and tools that ensure all project activities, outputs, and documentation meet high standards of quality, safety, and compliance. The plan defines structured processes for conducting meetings, reviewing deliverables and milestones, validating dissemination materials, and monitoring risks throughout the project duration. It also incorporates Health, Safety and Environment (HSE) considerations, ensuring that all partners follow appropriate protocols. The QCP serves as a central reference for maintaining consistency, transparency, and reliable project management across the consortium.
