Unlike the NGT, the Delphi technique involves creating a series of open-ended questions for group members.
Step-by-step explanation:
An open-ended query is not replied by a "yes" or "no" answer or by a set answer. Questions open to the public are presented as a declaration requesting a response. The solution is equivalent to knowledge that the questioner is already acquainted with.
Types of open-ended questions:
- Tell me your supervisory partnership.
- How do you look forward to the future?
- In this photograph, tell me about the children What's the government's purpose?
- Why have you selected the reply?
