Welcome to the Delphi Decision Aid!

Delphi is a data-gathering tool to aid in the anonymous survey of expert judgments, obtained in a series of rounds, ultimately for forecasting purposes. This can have (but is not limited to) the following applications:

• New product forecasts
• Personnel selection
• Estimating the effect of a change in a marketing program
• Predicting outcomes in conflict situations

Delphi is designed only for use with questions that yield either rankings or quantitative estimates.

This site helps you to:

• Select experts
• Develop questions and scales
• Obtain responses from the experts
• Summarize a report after each round

It also allows access to relevant literature including, in some cases, full-text articles.

If you wish to administer a session, please create a new administrator account.

Program development
	Based on suggestions from users, we have upgraded the Delphi software. Funds for the upgrade were provided by the Ehrenberg-Bass Institute at the University of South Australia and completed by St. Louis Integration. This Delphi program was developed by J. Scott Armstrong and was funded in part by the International Institute of Forecasters.
