About the i-Delphi System

The i-Delphi system is hosted on Windows 2000 and SQL (Structured Query Language database) servers operated by Interland, Inc., Atlanta, Georgia.

The i-Delphi system makes extensive use of Active Server Pages, a software method by which programs running on a web server generate pages destined for the user’s web browser. i-Delphi panelists interact with pages that are created as needed from records stored in a database. Project databases can be updated at any time. That system design enables i-Delphi projects to evolve quickly and continuously in response to panelists’ input.

Panelists’ contributions are recorded immediately in an SQL database. Summaries and tabulations may be requested by panelists at any time. That query capability, in addition to presentation of tabulations as part of many system-generated pages, leads panelists into reconsideration of responses in light of other panelists’ contributions. Feedback and re-iteration through project elements are central to the Delphi method.

The i-Delphi system was built using standard web technology. The Internet's broad reach and availability enable panels to be organized without regard to distance, time-zone differences, scheduling considerations, or necessity to meet in person. Specialized equipment, facilities, and software are not required. Participation from the privacy of one’s home or office assures complete anonymity of contributions and elimination of inhibitions and pressures that can have detrimental influences on face-to-face meetings.

All information associated with i-Delphi projects and panelists is confidential and protected by elaborate security precautions. Each project has its own passwords and internal controls to assure that only authorized individuals can participate and gain access to results. Specific responses are never associated with identified panelists.

The i-Delphi system offers many alternative methods for presenting information and entering responses, ranging from input of free-form text or numbers to selection from pre-existing lists. Each component of an i-Delphi project is implemented using the most appropriate presentation and response formats. Background and instructional information can be incorporated into a project as required, using all web features, including text, graphics, audio, and video.

Panelists are frequently asked to rate the confidence they attach to specific responses, or to assess their own experience or expertise which underlie specific responses. When appropriate and useful, responses are given greater or less weight based on those self-assessments or other information provided by panelists.
