Traditional software improvement methodsattempted to solve all the problems presented in the current phase. The New software agilequality improvement method optimized it by subdivided the improvement process intomore tiny sub-phases. And rescale the quality monitoring work percentage of everysub-phase, reduce the impact time, make early exposure to the various problems, and try toimprove the process step-by-step.This article also shows the significant effect on the project after using the new agilequality improvement methods. Within this15months test period, the project teameffectively and perseveringly executed this newly improved method. The result of thepractice proves that software agile quality improvement method balance product qualityand cost of quality for the companies in the process of quality continuous processimprovement.
