The Deliverable 9.1.2 is part of the Work Package 9 ‘Communication, Dissemination and Exploitation’, of the ASTEP project and gives a detailed description of the project’s communication strategy for outreach to public and the wider stakeholders. This is the second version of the entitled ‘Communication strategy’ report, documenting the effort specifically under Task 9.1 ‘Communication Strategy Activities’. This document presents a comprehensive plan for the communication activities throughout the project’s lifetime. It is a practical document intended to be used as a working reference for the project partners. It lays out key targets, responsibilities, processes and indicative timings. Well planned and regular efforts including all partners will be required to amplify the key messages of the project, its activities, the expected results, and how different target groups can benefit from these results. The plan reflects the European Union’s best practice guidance for communication H2020 projects and is structured around the “6W’s” approach: ● Why? What are our objectives and why is it important for us to communicate? ● Who? Target audiences / stakeholder groups and the different communication objectives, messages, and mode of delivery applicable to them. ● What? Key communication messages and key results to be disseminated. ● Where? Both geographic location of target audiences and the communications channels that will provide the ability to reach them. ● When? Timing and frequency of all planned communication activities throughout the duration of the project, with respect to the internal resource planning, expected emergence of key results and external events and opportunities. ● How? Both using the right channels, language, and branding, and how all communications and dissemination related activity will be coordinated, managed and measured effectively. Following this structure, the first part of this document explains the rationale why a communication strategy is needed and the main objectives of this strategy. The targeted audience is then set and appropriate key messages are presented for each stakeholder group. This is followed by a list of communication means through which the relevant audiences can be reached. The final section discusses internal processes and tools (e.g. events calendar, activities plan) set up to ensure the timely exchange of information between partners. The Key Performance Indicators (KPIs) are then highlighted and the importance of evaluating the activities is explained.
