The PYSOLO Dissemination and Communication Plan (DCP) offers a strategy to maximise the project impact by addressing relevant stakeholder and target groups via suitable channels and instruments. The plan describes online and offline activities and materials, defines strategic goals based on key performance indicators (KPIs) and risk assessment, and presents means of verification of the implemented activities and materials. It also presents the project’s visual identity and describes relevant standards and procedures. This document is the first version of D5.1 Dissemination and communication plan, which acts as a living document.
