Is Delphi qualitative or quantitative?
qualitative
The Delphi method is a formal, in-depth systematic qualitative methodology which was first studied by a team at the RAND Corporation in 1950, who made multiple practical applications of the method (Dalkey & Helmer, 1963).
What is a disadvantage of the Delphi technique?
Cons: There are a lack of clear methodological guidelines. Continued commitment is required from participants who are being asked a similar question multiple times. There is no evidence of reliability (i.e. if two panels received the same question they may not come to the same consensus)
What is the main advantage of Delphi method?
Some of the benefits of applying the Delphi technique are: It provides different analysis and information on complex issues. Highly objective thinking is formed. Decisions based on experts are likely to be efficient. It is possible to have a wide variety of options to decide.

How long does a Delphi study take?
Three rounds, which would typically take four months, often suffice (Stone Fish & Busby, 2005). Panellists form the lynchpin of the Delphi, and clear inclusion criteria should be applied and outlined as a means of evaluating the results and establishing the study’s potential relevance to other settings and populations.
