Given various budgetary and time constraints, to meet the project's stated objectives Apheis chose in a first phase to narrow the project's scope and investigate the information needs and behavior of a single, key target audience from among the large number of target audiences that require information on the impact of air pollution on public health. From all the potential target audiences that deserved investigation, we chose government policy makers and influencers, since through their actions this group probably has the greatest impact of all our target audiences on improving public health. To gain the best possible understanding of the chosen target audience, we decided to concentrate.
