Process
The Delphi process, step by step
From a sharp question to a reported consensus
A Delphi study runs in six steps: define the question, select the expert panel, run an open first round, feed back an anonymized summary in round two, repeat until a predefined stopping rule is met, then report the result with any persistent disagreement. Save it as a planning aid for your first panel study.
Where this appears
What's in this process
- Define the question: A sharp, answerable problem statement is half the battle.
- Select the expert panel: Recruit real expertise and seek diversity of perspective, not just agreement.
- Round one: Often open-ended, to surface the full range of considerations.
- Round two: Experts see the anonymized summary and re-answer, often with rating scales.
- Subsequent rounds: Repeat until the predefined consensus threshold or stopping rule is met.
- Synthesize: Report the final position, the level of consensus and any persistent disagreement.
