Prism Communications proposes a three phase PR campaign to improve GirlGuiding UK's image and increase student volunteers by 20%. Phase 1 involves a press launch announcing a "Hi-Five" video project featuring current volunteers. Phase 2 has those volunteers create weekly social media updates over 100 days to build an online fan base. Phase 3 holds a celebration event where the fan base can meet the volunteers. Progress and success will be measured through metrics like media coverage, website traffic, and surveys.
