With the Delphi Technique, there is no direct group interaction. The participants do not engage in conversation with each other, cannot discuss with each other and do not build on each other’s ideas, as is done in brainstorming.
With the Delphi Technique, you gain insight into each other’s individual ideas and later, in the second session, you can delve into those and further build upon those. Whereas a brainstorming session is known for interactive group meetings, the Delphi Method involves individually thinking about the problem.
