Collecting high-quality qualitative data is time consuming and expensive. The World Café method can save time and money while still collecting qualitative data of high quality. This method is particularly useful when the collective knowledge of a large group is needed to solve a problem or to acquire insights. Despite growing interest in the World Café method, how it should be conducted has not been clearly described. To address this, we have developed a Three-Phase Blueprint that describes how to host a rigorous World Café based on a literature review and our own experience. By following the structured approach of the Three-Phase Blueprint, researchers can exploit the advantages of the World Café method.
