Delphi Technique
Delphi Technique: A Consensus-Building Method
The Delphi Technique is a method designed to generate consensus. In this process, a group of experts provides iterative opinions on a specific topic until they converge to a common agreement. Evidently, the key benefit of this technique is its ability to reduce the differences in opinions among experts and foster collaboration.
The RAND Corporation developed this technique in the 1950s. Various fields and organizations adopted this technique since them, including project management.

Steps to Use the Delphi Technique
For a team to successfully implement the Delphi Technique, must follow some given steps. While these steps can be adapted depending on the specific problem and participants, the typical process includes:
- Choose a Facilitator – In reality, the facilitator plays a crucial role in this method. Basically, this person must remain neutral and impartial throughout the process.
- Select the Experts – The organization must choose a diverse group of experts, representing different fields to ensure varied opinions. Additionally, everyone must recognize them as experts in their respective areas. When selecting the experts, the organization can maintain anonymity, meaning no one will know who the others are.
- Share the Problem with Experts – The organization should present the problem to the experts. They need sufficient time to analyze, gather information, and form their opinions, which they will later share with the other experts and the facilitator.
- Distribute the First Questionnaire and Analyze Results – The facilitator sends the first questionnaire to the experts, collects their responses, and then analyzes the results. The facilitator should group similar answers and consequently remove irrelevant information. The facilitator should present the result anonymously, even if the experts know each other, ensuring that the identification of the experts is not possible. Generally, the facilitator should show the results in a statistical format.
- Distribute the Second Questionnaire and Analyze Results – Following, the facilitator sends a second questionnaire, designed to deepen the discussion based on the first round’s results. The facilitator must analyze the results again.
- Repeat the Process – The facilitator repeats this process until everyone reaches a consensus. Finally, once the team obtains consensus, the facilitator can share the results with the experts.
Advantages of the Delphi Technique
The Delphi Technique is an effective way to gather expert opinions while minimizing biases. Some of its main advantages include, for example:
- Experts’ opinions typically lead to efficient decisions.
- It offers diverse and different perspectives on complex issues.
- Anonymity encourages experts to share more open and creative opinions, knowing that no one will identify their responses.
- After each round, experts have the opportunity to revise their opinions, allowing for more thoughtful as well as refined input.
- Experts can focus solely on the issue at hand, without the influence of outside factors.
- Specially helpful during planning poker.
Challenges of the Delphi Technique
While the Delphi Technique offers many benefits, it also has some drawbacks, such as:
- Following the first round, opinions may become biased, potentially leading to suboptimal results.
- The process can be time-consuming as it involves several stages and interactions before reaching a conclusion.
- It can be costly, basically, because experts are often high-priced resources.
- Furthermore, it is necessary to manage clear communication carefully to minimize potential misunderstandings.
By understanding both the advantages and challenges, organizations can effectively decide when to use the Delphi Technique for consensus-building.
