What is the Modified Delphi Process?

The Modified Delphi Process is a systematic and structured process designed to help a group of experts reach consensus on a particular topic. It uses a combination of in-depth discussions and anonymous, iterative surveys to provide focus and prioritization to the problem-solving process. It’s particularly useful for complex problems that require the collective intelligence of the group (Nasa et al., 2021a).

The Task 1 Coordinating Body will use this process to reach consensus on the top priorities among the Hazards/risks, PHEP capabilities/gaps, and At-risk populations for the region that will eventually be included a 5-year work plan for the soon-to-be-established CDC Center for Public Health Emergency Preparedness and Response for Region VIII.

How does it work?

The flowchart below gives a basic outline of how the process is carried out. The “Delphi rounds” usually consist of three rounds of surveying.

What is the role of Coordinating Body?

Each member of the Coordinating Body was specifically chosen based on their position and focus area to create a panel that contains both the broad perspective and expertise needed for the success of this project. Each Coordinating Body member will participate in a series of discussion-based meetings, in addition to anonymously completing the surveys for the Modified Delphi Process. It's important that each member remains anonymous so that they feel comfortable sharing information/opinions that could be controversial (Nasa et al., 2021a).
