| dc.description.abstract | Six Sigma originated in the 1980s. It was originally used by Motorola to reform the company’s production process. It has developed up to this day. Although it isn’t a brand-new concept and tool, but it has its own unique features. It makes good use of human resources, data, statistical tools, etc., to improve process quality and reduce defects or errors. Among them, the step of Six Sigma, DMAIC, is often used as one of the tools for process improvement.
This study takes the domestic S company as an example, and discusses the improvement of the procurement approval process. In recent years, the S company′s production pattern has tended to be more and more diversified. In order to meet customer needs, in addition to good quality, fast delivery is due to manpower and equipment. The production capacity is limited, and may be rendered difficult to compete on schedule to reach such quality. In order to relieve the capacity load, private enterprises were entrusted to process and produce, which resulted in a demand for purchase cases. The purchase cases covered the entire process of material procurement from raw materials to finished products, labor outsourcing, and outsourcing of materials, especially This part of capacity outsourcing is even more urgent. Therefore, reducing unnecessary purchase procedures is a key factor in shortening the approval cycle for this study. How to use different improvement methods, steps, and tools to reduce personnel negligence and accelerate process efficiency is the primary task.
In order to achieve S company’s vision and goals, it is necessary to innovate to break through the current situation and enhance its strength. This study uses the DMAIC method of six sigma to explore how to improve outdated management practices and reduce the value-added operation steps in the procurement process, and solve the problem in the implementation process Based on the problems that arise, the theoretical framework and practical application methods are used to propose specific procurement process improvement strategies to assist companies in improving processes, shortening personnel work time, and increasing corporate competitiveness.
The research results show that through the six sigma DMAIC method, it can effectively help S company find the factors that affect the procurement process and the degree of problems caused by these factors. Then, use the characteristic factor map to find the true cause, and target these key factors. System structure analysis, improvement countermeasures, and continuous control are expected to be able to simplify processes, unify operations, and reduce labor costs. | en_US |
