Wideband Delphi is a method of group facilitation used in project management to help teams agree on issues or estimates related to the project. It is a planned method in which a group of experts give their separate thoughts on a certain topic or issue, followed by a guided discussion to come to a decision.
Usually, the following steps make up the Wideband Delphi method:
- Planning: The facilitator or project manager chooses the issue or topic to be discussed and a group of experts to take part in the process.
- Individual Estimation: Each expert is asked to give an estimate or opinion on the topic or issue on their own. The facilitator takes notes on the results and makes a summary of them.
- Group Discussion: The group is then brought together to talk about the results and come to an estimate or opinion that everyone agrees on. The facilitator leads the discussion and encourages the group to talk about why they came up with their own estimates and what assumptions they were based on.
- Reiteration: The process can be done more than once until everyone in the group agrees on the subject or issue.
Wideband Delphi is often used in project management to do things like assess risks, estimate projects, and gather requirements. It is especially helpful when dealing with project issues that are complicated or uncertain and where the opinions of multiple experts can help give a more accurate estimate or assessment. The technique is meant to lessen the effect of each person’s biases or judgements and encourage a group approach to making decisions.
