Profile: The Survey is used to map communication channels, participatory interventions, feedback and response mechanisms in Yemen to inform AAP mechanisms. The Survey is composed of two sections: The first maps communication channels used by humanitarian organizations across geographical locations in Yemen. The second maps channels and entry points particularly for feedback, complaint, and response mechanisms (FCRMs), including email addresses, phone numbers, WhatsApp groups and other social media. Why to Use the Template: The Survey is the first step to identify existing communication, participatory and feedback channels. Outcomes can inform two-way communication, including FCRM, at the agency or interagency levels. How to Use the Tool: The Template can be used to develop a context-appropriate survey based on indicative questions and responses. It can be adapted to different countries or organizations. Additional questions and free text can be included, as needed.
