With traditional testing processes, there are many issues of unacceptable defects found after the end of testing processes. To solve this problem, we applied quality management according to Six Sigmas quality improvements. From the principles of DMAIC, they found the most of mistakes came from runtime error, logical error and syntax error at 3.83%, 2.83% and 5.50%, respectively. This research consists of five stages of problem identification, the root cause analysis to find out the problems, drawn tree and fishbone diagrams help to analyze and solve problems. The quality improvement concepts were implement by using experiment designed techniques which controlled by standard software testing in the final step to ensure that the problems will not occur again. The results show that using quality management with the principles of DMAIC integration can reduce defects referring to Run Time error from 3.83%, 2.83%, 5.50% to 2.67%, 1.33%, 3.83%. This benefit will improve the confidence level, and raise the good image of the company.
