Pathfinder was conducting a baseline health survey in the Mwanza & Shinyanga regions of Tanzania. The survey was based on WHO guidelines and included over 150 questions in various formats. Pathfinder decided to develop a mobile app of the entire survey to streamline the entire process, ensure data integrity, validate data entry and monitor survey results in realtime. Ongoza worked with Pathfinder to understand their requirements, translate the requirements into layouts then build the application. Our technical team even accompanied the Pathfinder field staff to test the final product in the field and deploy across the surveyor’s handsets.
