In an extreme event or major disaster, very often there are both alternative actions that might be considered and far more requests for actions than can be executed immediately. The relative desirability of each option for action could be a collaborative expression of a significant number of emergency managers and experts trying to manage the most desirable alternatives at any given time, in real time. The Delphi Decision Maker can satisfy these needs given that anyone can vote or change their vote on any options, and voting and scaling are used to promote a group understanding.

Scale of Group Opinion is offered
as a feedback mechanism. This reflects the group's
opinion at any one moment in time.

Even when all experts in a group may not be able to participate at the moment, or some may be unqualified to vote on a particular matter, nonetheless, a decision must be made. This system is conducive for decision making given the worst of conditions, utilizing the information as well as the experts to their fullest capacity. In a disaster, it may appear that there are only poor selections after such a tragic event has occurred. However, a best decision must still be made, thus minimizing potential future damages and hence, maximizing the best obtainable outcome for the challenges that lay ahead. A dynamic Delphi system will support real time decision making for virtual groups working in a changing environment. The Internet provides opportunity and lessens previous geographic boundaries to a great extent. The system is available online and is accessible anywhere there is Internet connectivity and a browser.
