What is the process of combining the information collected from various points i.e. focus groups / interviews to inform Delphi questions? Does anyone have a suitable reference. I did a quick search but couldn't find much.
I don't think there is an concrete procedure for writing questions for qualitative interviews in general, or Delphi elicitations in particular. I would recommend getting some key informants or other experts to look over your questions before you send them out.
