Student in Human Resource Management, University of Tehran, Tehran, Iran Journal Article 2013 10 19 Today, many organizations plan to implement and exploit ERP system due to its numerous benefits. Despite these advantages, many adopting organizations have failed to achieve their intended goals through utilizing ERP system. Among other factors, organizational characteristics have been proposed as one of the effective factors which can influence ERP success in both implementation and post-implementation stages. This study examines the impact of Organizational Structure as a potential factor on ERP post-implementation success in Iranian adopting organizations. A research model is developed to test fifteen hypothesized relations among the variables. Data is gathered from every adopting organization using a standard questionnaire. Then, Structural Equation Modelling (SEM) Method and Partial Least Squares (PLS) Algorithm are used for data analysis. The findings confirm the impact of Organizational Structure on ERP post-implementation success and indicate how Structural Dimensions affect ERP success facets. https://jitm.ut.ac.ir/article_50050_a441339e8276181798cf67ebd7739f85.pdf
