||The development and spread of new technology and the internet has opened a new world of possibilities to gather data and create information in a crisis. However, it is not clear which information field managers require to make the best possible decisions. As a result, it is difficult for volunteers, technology developers, and others, to collect and analyze data that results in information that is accessible and actionable for decision makers. To understand the information requirements of humanitarian responders, a workshop was conducted, bringing together eighteen experienced humanitarian responders. The results of the workshop include preliminary frameworks for decisions and information requirements that are common during the initial phases of a sudden onset disaster. These frameworks will help volunteer and technical communities to understand the information field decision-makers require to make the best possible decisions.
