As a result, 219 respondents were used for data analysis (41.95 percent). This study utilizes Partial Least Squares (PLS) to confirm the hypotheses–a variance-based Structural Equation Modeling (SEM) approach. The results showed that at 0.05 significance level, cooperation has a positive effect on the control. Moreover, cooperation and improvement have a positive effect on the performance, and performance has a positive effect on outsourcing long-term relationships.
