Our Work Flow

Build a comprehensive strategy

Knowing whom to address is as critical as knowing what to say. Full Duplex thoroughly researches key participants, opinions and gathering places, threshing the facts from the confusion of misinformation and disinformation. Then we help clients with strategic action based on the best information available.

Manage the issue

To achieve meaningful results, the power and reach of online platforms must be combined with traditional media and public affairs efforts. We develop strategy-driven stories, manage the online information flow and assemble networks to ensure a robust and positive presence.

Measure progress

We check our progress at every stage toward accomplishing our clients’ goals. By setting concrete benchmarks and keeping a steady eye on their value and relevance, we keep pace with the market and maintain focus on the issue and how it evolves for its full life cycle.
