Story-Based Inquiry is a field-tested method for defining, deepening and organizing investigations. It consists of four tools -- a hypothesis, a timeline, a source map and a master file -- that enable you to structure a story as you conduct research. The process is simple, and it provides big gains in efficiency. Since its publication by UNESCO in 2009, Story-Based Inquiry has been used by thousands of journalists and translated into more than a dozen languages. In this session the authors will take you through the process, using the example of a recent transnational investigation into agricultural pollution. The session will be of immediate value to reporters who have not yet undertaken long-form work, reporters who have difficulty conceptualizing and pitching a project, and those stuck in the middle of an ambitious project and can't get control of their material.
