Delphi's Second Stage of Development
Early Delphi projects used printed questionnaires, manual
analyses, and
the mails. Results were excellent, but from today's perspective the process was slow, cumbersome, and expensive. Starting
in the 1970's, Delphi projects were undertaken in meetings, using new
computer technologies. Participants entered their opinions secretly via small, hand-held terminals.
A computer would tabulate responses
and display them to the group. Those
innovations provided both advantages and
disadvantages. Face-to-face discussions facilitated exchange of ideas. The
moderator could keep a group on focus and moving forward. Immediate feedback enabled multiple
rounds to be compressed into a few meetings. On the other
hand, only contributions entered via terminals could be anonymous. Views of individual panelists,
if frankly expressed, would become obvious during discussions. That and other group
pressures diminished the likelihood of full and honest participation by all panelists.
Hand-held terminals had limited capabilities. Then as now, meetings required
synchronizing schedules and significant expense for travel and lodging.
