UNICEF Pacific faced the problem of how to engage and empower Pacific youth more through social media. The proposed solution was to invite Pacific youth to contribute to the design of a climate change game, the ‘Pacific Climate Challenge’. Such an approach presents challenges including how to effectively engage co-creators, how co-creators will communicate and contribute, how contributions will be managed in a virtual environment and how decision making will be managed. This paper explores co-creation in a virtual environment using Participatory Design (PD) theory. Our findings highlight the importance of managing communication with a geographically dispersed team, managing development in an unstructured environment, the importance of leadership and access to both knowledge and skills. We identified that in co-creation environments as compared with typical PD environments, the development process can be less structured with no clear management hierarchy, roles evolve and change and standard success criteria may not apply.
