Zhrnutie	The multi-source focus group method extends the standard focus group design by deliberately recruiting participants from two or more distinct stakeholder groups — for example, clinicians and patients, teachers and students, or managers and frontline staff. Separate sessions are held for each source group using a shared discussion protocol, and the resulting data are analyzed both within each group and across groups to reveal convergences, tensions, and perspectives that no single-source design could uncover.	The Delphi method is a structured, iterative survey technique developed by Norman Dalkey and Olaf Helmer at the RAND Corporation in 1963 for eliciting and converging expert opinion on complex topics where empirical data are unavailable or insufficient. It collects independent judgements from a geographically dispersed expert panel over multiple anonymous rounds, feeding aggregated results back to participants after each round so they can revise their views in light of the group's collective position.
