Abstract: The performance of construction companies is crucial for the economic development of every country and there are various factors which affect their performance of Construction Company. Past studies on project performance have been skewed towards project factors such as client, contractor, consultant and material. Through the literature review, it was noticed that a research gap exists, whereby, for the success of a project, not only are project factors important, but organizational factors are important too. Taking a lead from here, the most important organizational factors, such as leadership, organizational culture, innovation and learning organization were chosen and used in this study to examine and investigate the impact of these organizational factors on project performance. Therefore, the objective of this study was to examine and investigate the impact of project and organizational factors on the project performance of construction companies in Iraq. A pilot study was carried out and the instrument reliability was ascertained. The population for this study was the construction companies in Iraq registered with the industry of construction and housing under the level 7 category. This quantitative study was carried out with a survey questionnaire. 500 questionnaires were sent to managers (Construction Manager, Project manager, Project executive, Site Supervisor) of construction companies and 411 responses were received with a response rate of 33.61%. The collected data were analyzed using the Statistical Package for Social Science version 25 (SPSS) for descriptive, reliability, validity and relative importance index analysis and Measurement and Structural Model using Partial Least Square Structural Equation Modeling (PLS-SEM) technique. The results of the study indicate that organizational factors have a greater significant impact on project performance over project factors. Thus, the outcome of the study is useful for the construction industry practitioners to understand the importance of organizational factors and to implement them in their organizations to improve project performance.
