Information technology can affect the performance of human resources, as it provides assistance to raise performance and provide the best, For the purpose of clarifying the impact of information technology on the performance of human resources, a number of research forms were distributed in this research, (140) forms included the( information technology )variable represented by three variables(physical Components, software and human components) ,the dependent variable (human resource performance ) included two sub-variables (Efficiency and Effectiveness). Numerical results showed the strength of the relationship between all research variables. The results also showed a significant effect of all information technology variables on performance variables. The effect of mediating variables such as (competition, economic factors) can be found as mediating variables that affect performance.
