During the last three decades, much study has been conducted on the impact of information technology (IT) on productivity
at various levels. Many of the studies consider IT implementation but emphasize the role of complementary investments that enhance and complement the IT implementation. Therefore, complementary investments, such as human capital, quality assurance, total quality management program, business process reengineering and organizational infrastructures, are proposed as the key to realizing information technology values. In this article, an effort has been made to provide satisfactory evidence from 200 Iranian car part suppliers to show that IT implementation, when rationally backed up by Organizational Infrastructures, will lead to a considerable improvement in firm performance. Results show that emphasis on organizational infrastructures, including; empowerment, decentralization, training, team work, process management and a change in interaction with suppliers, moderates the relationship between IT and firm performance.
