Human resource managers play a wide variety of roles in improving organizational performance.

The main aim of the research is to draw a contextual model which illustrates the position of intellectual capital in the relationship between human resource managers’ responsibilities and organizational performance. In this research, mediator variable, independent variable, and dependent variable were respectively allocated to intellectual capital, human resource managers’ responsibilities, and organizational performance. The sample includes 156 managers which were selected from middle and top managers of National Iranian Oil Company by implementing cluster-chance method. Confirmatory Factor Analysis (CFA) was employed to examine the indicators of the studied variables and to evaluate the construct validity; Structural Equations Method is adopted in order to test the research hypotheses. The results indicated that human resource mangers’ operations considerably influence organizational performance through the medium of intellectual capital. In the contextual model, recruitment and selection as well as performance appraisal have the greatest factorial load among the human resource mangers’ practices, and the greatest factorial load is allocated to structural capital among three classes of intellectual capitals.
