Összefoglaló	The Multi-source Delphi Technique is a structured, iterative consensus-building method that deliberately recruits expert panellists from multiple, distinct stakeholder groups or knowledge sources. By ensuring that no single professional community or institution dominates the panel, it reduces homogeneity bias and captures a broader range of perspectives than a conventional single-group Delphi. Panellists respond anonymously across successive rounds, receiving aggregated group feedback between rounds until consensus or a stable level of agreement is reached.	The Delphi technique is a structured, multi-round data collection method that harvests and refines expert opinion through iterative questionnaires and controlled feedback. Developed at RAND Corporation in the 1950s, it is designed to converge a dispersed expert panel toward a reliable consensus on complex, uncertain, or future-oriented questions — without the conformity pressures of face-to-face group discussion.
