Based on the extensive literature review and the philosophy of integration of quality tools, the paper develops integrated quality information system (IQIS) software, and applies it to a manufacturing company. The software integrates the quality tools as well as the process quality information. It provides guidance for locating bottleneck process through integrated data analysis and also supports six sigma process improvement. The result shows that the application of IQIS can optimize the process of design and manufacturing, shorten the cycle time of product, reduce the cost, and realize quality improvement continuously
