| Evaluate discrepancies among the different scorings and evaluate
the level of consensus | Face to face discussion and negociation
GroupSystem | The deviation of each individual scoring from the average
scoring obtained for a criterion by a scenario is examined. Discussion
helps improving the common understanding of the  scenario and may
lead to a modification of scoring. Finally, the level of consensus about
the scenario is evaluated as low or high. In the former case a quantitative
evaluation must be performed whereas the evaluation of this scenario stops
in the latter case. |
