Linkage between Supply Chain Management Practice and Job Satisfaction, Delegation of Authority to Improve Corporate Performance

The first goal of this study to verify the hypothesis that Supply Chain Management practice affects positively the corporate performances of companies in Korea as the samples of the study. The second goal is to confirm further hypotheses which joba satisfaction and delegation of authority show positive moderating effect on the relationship between Supply Chain Management practice capacity and the performance respectively. To accomplish these goals, the authors conducted a series of surveys and empirical analyses utilizing reliability analysis, validity check, regression model analysis and moderate regression model analysis. Those analyses brought the result that Supply Chain Management practice has positive effect on the performance in Korean sample companies. Further research analyses showed the results that delegation of authority demonstrates positive moderating effect on relationship between Supply Chain Management practice and the performances, while job satisfaction does not. lt implies an managerial implication that implementing investments on and making efforts on Supply Chain Management practice and delegation of authority concurrently can provide companies with more improvement in the performance because of a synergistic effect between the two. Moreover, one possible reason that job satisfaction does not demonstrates synergetic effect can be explained by the characteristic that job satisfaction have to be sought over long, not short, time span to expect improvements in performance in connection with other types of managerial efforts or investments.
