how is the delphi method conducted 
the group facilitator selects a group of experts based on the topic being examined and sends them a questionnaire with instructions to comment on each topic based on their personal opinion experience or previous research the facilitator groups the comments from the returned questionnaires and sends copies to each participant along with the opportunity to comment further at the end of this session the questionnaires are returned to the facilitator who decides if another round is necessary or if the results are ready for publishing this process can be repeated multiple times until a general sense of consensus is reached
