Sonjara built the Food Frequency Method Online (FFMO) , a cloud-based open source prototype for NGOs and governments surveying food security and child survival. Based on the Helen Keller International Food Frequency Method for Vitamin A Deficiency, the FFMO maps current paper-based food frequency survey methods to measure malnutrition in under-five year old's by household. Not only does the FFMO make the scientifically validated method more efficient, but it also brings in just in time open source data into the survey design process. For example, survey managers select dates of the survey by looking at critical temperature and precipitation data from the World Bank for the target country, allowing them to decide when the best time to perform the survey, based on their goals. Managers also select and identify communities to be surveyed using Google maps. The FFMO also automatically tracks the status of interviewers and calculates questionnaire results. The tool can bring in additional outside data to put the results into context, making for better design of appropriate interventions. Finally, the FFMO makes the data exportable to be shared back with the food security/child survival community.
