The study population was selected using the Cochran formula and cluster ýsamplingþ.þý Robbins Organizational Structure Questionnaire and Delone and Mclean’s Management Information ýSystems Questionnaire were used to collect data. Data were analyzed using Spearman correlation test in SPSS ýsoftware and Structural Equation Modeling in Amos software.
A significant negative relationship was found between the MISs and dimensions of centralization and complexity (-ýý0.325 and -0.543, respectively). Moreover, a significant direct relationship was found between MISs and the ýdimension of formalization (0.314). The impact of MISs on centralization, complexity, and formalization was, ýrespectively, calculated as -0.85, -0.74, and 0.69 using structural equation modeling (SEM).
