Therefore, during the Rand UCLA Appropriateness Method
meeting, no indications are discarded between rounds and,
consequently, no potential information is lost. In the nominal
group method, the meeting involves rating, discussing and, finally
re-rating a series of items. A panel meeting at the end of the Delphi
procedure may be useful when reaching a consensus is difficult.
The best strategy would be a physical meeting at the end of the last
round to exchange views and resolve uncertainties. However, the
meeting should be well structured and should take place under
favourable conditions(good surrounding and general environment)
[47] with a moderator to contain the influence of dominant
personalities. Studies on methods involving face-to-face interaction
show that the way a meeting is structured and organized affects the
group interactions [48] and influences the manner in which the
group produces results.
