Managers can more successfully understand their personal characteristics and attributes, in order to steer and manage them correctly, and convey this feeling and message to them, with their ideas and thoughts in the organization being considered.

To calculate the formal validity, content validity (CVR and CVI) and construct validity were used. After analyzing the distribution of data as normal, a parametric test was used. Finally, the hypothesis test was performed using Pearson correlation method and all the hypotheses were confirmed and the final model of communication skills was developed.
