Integration between the system of statistical quality control and the production system on time and its reflection on improving quality and reducing costs, with reference to the Japanese and American experience
The administrative and economic literature indicates that cost and quality are among the main factors that affect the competitiveness of organizations locally and internationally. These two factors are the main reasons for the trade imbalance between the advanced industrial countries, especially Japan and the United States of America. Japan, away from perceptions, has become an economic giant and managed to control the markets by offering high quality products at competitive prices, and as a result of the panic generated by the trade imbalance, attention has been paid to an important fact related to Japanese products, this fact is that the quality of Japanese products continues In addition to the improvement in its industrial costs compared to those in the United States of America. In this context, the question that arises is why does Japan achieve low manufacturing costs? The traditional view of the relationship between cost and quality assumes that quality is a distinctive quality that falls within the cost of a single unit, and cost is a quality function that increases due to its direct relationship to quality. This formula sees quality as an economic good and assumes that producing high-quality goods will cost more because it needs better materials, an examination of operations and equipment. This interpretation intersects with the Japanese model. In this context, many researchers and interested people tried to explain the reasons behind the success of the Japanese model, some of whom pointed to low manufacturing costs, high investment in technology, economies of scale, learning curve, while Deming believes that the key to Japanese success is a quality system that is based on a program of quality control Statistical ((SQC and real-time production system) (JIT) as well as other reasons.
The main objective of this study is to investigate the hypothesis that the implementation of (SQC and JIT) will lead to a substantial improvement in product quality and that high quality will ultimately reduce manufacturing costs.
The study dealt with a review on quality, quality control, and on-time production in order to expand the cognitive space of these concepts to prepare the intellectual ground for areas of integration and discuss their impact on cost and quality. Finally, a reference to the problems that may be encountered in their use in industries and recommendations for overcoming these problems.
