The Delphi Method is particularly popular in companies, among other things, in the context of project management. Differences of opinion between members of internal project groups can often lead to the failure of an entire development process. With the Delphi Method in project management, consensus can be created in processes again with the help of experts. The assessment of experts helps to find a joint solution, independent of the influence of individual persons, for a specific problem. Furthermore, the Delphi method is also used for estimation tasks. For example, when developing a new product, certain relevant trends can be recognised and evaluated by experts. In addition to its application in companies, the Delphi method is also essential in the medical field. For example, it is used to create guidelines, with the advantage that multiple treating physicians (experts) can be included.
