The survey was conducted among meddle and senior managers and respondents were asked to express the opinions related to the effects organizational learning as mediator in relationship between management and organizational resilience. Knowledge management had an effect on organizational resilience. Organizational learning did not have a direct effect on organizational resilience, except through the full mediation of Knowledge management. This suggests that without Knowledge management, public organizations of Iran may not improve their level of resilience. Utilizing a cross-sectional design with questionnaires is one of the limitations of this study. The results may be different in the private sector. A future research strategy that may overcome this limitation is one that involves longitudinal studies in which flow of study variables can be followed over time. In addition, using objective measures, archival data for some variables, may give results that are more objective.
