Developing Integrated Continuous Improvement Model for Competitiveness of Ethiopian Automotive Industry

Abstract

The purpose of this study is to examine the relationship and difference among the continuous improvement tools such as just in time (JIT), total quality management (TQM), and lean six sigma (LSS). It also emphasizes these variable implementations and practices for competitiveness and achievement of integrated model development with common and unique success factors for a company's better competitiveness. Besides, it provides a case application evaluation of the model with the Bishoftu Automotive industry. Comparative study of TQM, JIT, LSS uses available literature critical analysis and knowledge of state of the art for competitive advantage. An in-depth analysis showed that a continuous improvement (CI) approach is necessary for the survival of industries in the dynamic and competitive market. Firms have employed CI strategies such as TQM, JIT, and LSS. However, most studies have demonstrated that factors concerning distinct approaches have advantages and limits in their situation. The integrated method would lead to the best competitive organization and resolve the shortcomings of each CI program. A thorough review of quality management (QM) methodology offers some possible explanations of why specific methods alone could not give an enterprise an absolute competitive advantage. This study, therefore, established an integrated model using the most commonly recognized variables by most research findings and practices. The research is exceptional in its scope by giving an insight into the advancement of CI and quality management in the context of an integrated model and introduced two new factors on existing CI factors.
