Delphi Study
A structured, multi-round process where a facilitator gathers and synthesizes responses from a group of external experts or stakeholders to build consensus on a specific issue or decision. Each round involves summarizing feedback, refining questions, and redistributing it for further reflection, allowing participants to refine their views based on the group's input.
