This study aims to test the effect of sustainable supply chain management on customer relationship management, competitive advantage, and organizational performance by collecting and analyzing data from the Egyptian textile industry. A suggested research model shows the hypothesized relationship between sustainable supply chain management, customer relationship management, competitive advantage, and organizational performance. The proposed research model and hypotheses were tested using correlation analysis and structural equation modeling based on data collected from 148 companies working in the Egyptian textile industry. Statistical analysis of the collected data supports the positive relationship between sustainable supply chain management on one side and customer relationship management, competitive advantage, and organizational performance on the other. Additionally, statistical analysis supports the positive relationship between customer relationship management and competitive advantage from one side and organizational performance from the other side. Data were collected through an online survey from 147 supply chain managers in the Egyptian textile industry to test the research hypotheses. The results suggest that the successful implementation of sustainable supply chain management will help in improving customer relationship management, competitive advantage, and organizational performance.
