Abstract A future successful global marketer must develop an excellent quality management system that impresses users and continuously provides excellent, quality products in a timely manner through corporate management. The author proposes New JIT, a new management technology principle for manufacturing in the 21st century. New JIT contains hardware and software systems as next-generation technical principles for transforming management technology into the management strategy. The hardware system consists of the Toyota

It aims to ‘‘build quality in’’ using Total Quality Management (TQM) in the manufacturing process while following the principle of cost reduction. This is why Toyota often compared TPS and TQM to the two wheels of one vehicle (see Ohno, 1977; Toyota Motor Corp., 1987). To be able to manufacture vehicles that meet customer demands without fail, timely quality, cost and delivery (QCD) studies are important. To accomplish this, Toyota has positioned TPS and TQM as the two figurative pillars of our management technology principle (see Amasaka, 1989). As Fig. 1 shows, these two elements combine to flatten extreme curves and constantly raise mean values by maintaining and improving QCD research with TPS as the hardware technology and TQM as the software technology. As is widely known, use of the rational technique of statistical quality control (SQC) reduces fluctuations in and raises the average level of manufacturing quality as represented in the figure. From such meaning as well, it could perhaps be said that SQC is the root of manufacturing and the historical origin of TQM. Improvements in engineering quality are an urgent necessity in order to emerge victorious from extreme global competition in the area of quality (see Amasaka, 1989).

The JIT (see Womack et al., 1991) concept and approach renovated vehicle production at Toyota. As a result of worldwide favorable
