Delphi`s results show a change in participants` views in terms of consensus and stability, as shown by a trend: the evolution of consensus has been demonstrated by increasing the percentages of concordance, the convergence of the range with the standard deviations of importance ratings and a decrease in the number of comments. The stability was manifested by an upward trend in Kappa`s values. For this declaration, the percentages and margins of convergence did not fluctuate significantly, which again showed disagreements in the third round, which testifies to stability. Although there is only 0.06 changes between towers 2 and 3, the SD indicates that there is still convergence. The testimony became less important and ranked 3rd to 5th. This paper addresses the issue of stability testing methodology between successive Delphi cycles and the need to do so before analyzing the level or nature of consensus. It has been proposed that consensus should be the same as agreement and that agreement could be determined by: the results presented here show two points that can be used to improve Delphi studies in the future. First, the results showed that mean and SD can be used in combination with range and medians to show whether convergence occurred through movement toward a central trend. This is consistent with the results of Greatorex and Dexter . The magnitude of convergence, and thus the strength of convergence, is indicated by a comparison of the SD (aggregate strength of judgment) and the range (wider areas are an indication of outliers). Second, high or increasing levels of Kappa show the stability of the opinions of individuals within the group and the degree of adequacy between the towers….
