Muhtasari	The telephone-assisted Delphi Technique applies the classic iterative expert-consensus framework through structured telephone interviews rather than mailed or online questionnaires. Experts participate in sequential rounds of data collection by phone, enabling the researcher to clarify ambiguous responses in real time and reach consensus on complex, contested, or forward-looking questions without requiring participants to convene in person.	A structured interview is a data collection technique in which every participant is asked exactly the same pre-specified questions in the same order, using standardized wording. Because the interview schedule is fixed, responses across participants are directly comparable, enabling quantitative aggregation and statistical analysis. It sits at the most standardized end of the interview continuum, between the self-administered questionnaire and the semi-structured interview.
