Delphi process

The Delphi process, originating from the RAND Corporation in the 1950s, is a systematic method for achieving expert consensus. Its core principles are anonymity, iterative rounds with controlled feedback, and statistical aggregation of group responses. This structure mitigates biases common in face-to-face meetings, such as the halo effect or groupthink. The method is formally recognized as an expert opinion elicitation technique in ISO 31010:2019 (Risk management — Risk assessment techniques). It is particularly valuable for assessing risks characterized by high uncertainty and a lack of historical data, such as evaluating the privacy impacts of emerging technologies or forecasting future cybersecurity threats. Unlike a simple survey, its key differentiator is the iterative feedback loop, where anonymized results from each round are shared, allowing experts to revise their judgments and converge toward a more robust consensus.

In enterprise risk management, the Delphi process follows clear steps to enhance decision quality. Step 1: Define the problem and select experts. Clearly articulate the risk to be assessed (e.g., privacy risks of Generative AI on customer data) and recruit a diverse, anonymous panel of experts (legal, cybersecurity, IT, ethics). Step 2: Conduct the first round with an open-ended questionnaire to gather initial views on risk likelihood, impact, and potential controls. Step 3: A neutral facilitator anonymizes and synthesizes the responses into a structured questionnaire (e.g., using rating scales) for the second round, which is distributed along with a statistical summary (e.g., median, interquartile range) of the first round's results. Step 4: Iterate until consensus is reached, repeating Step 3 until the variance in expert opinions falls below a predefined threshold (e.g., >80% agreement). A global tech firm used this method to prioritize its top 5 AI ethics risks, leading to a 50% faster policy development cycle.

Taiwan enterprises face three primary challenges when implementing the Delphi process. First, sourcing a diverse panel of experts while maintaining true anonymity can be difficult, especially in niche industries where the expert community is small. The solution is to broaden the search to include academics, international consultants, and retired professionals, and to use a trusted third-party facilitator. Second, the process is highly dependent on the facilitator's skill. A biased or inexperienced facilitator can skew results during the feedback stage. This can be overcome by investing in professional training for internal staff or engaging external experts like Winners Consulting. Third, the multi-round process can be time-consuming, clashing with Taiwan's fast-paced business culture. To mitigate this, enterprises can leverage digital platforms to streamline communication and set clear timelines and milestones for each round to maintain momentum.
