Impact of CMMI High Maturity on Software Quality
with Pushpa Gadde
This paper discussed how software quality is improved using CMMI High Maturity processes in conjunction with Lean Six Sigma principles in CGI. Data for each release cycle were analyzed using bar graphs, control charts, trend analysis, and normality test and reviewed with project's team members. This gives opportunity for investigating abnormal trend and special causes. Many of these improvement opportunities turn in to Lean Six Sigma projects and findings were recorded as CAR report. Rayleigh model is used to predict and monitor performance throughout the software life-cycle. Project's data show that the testing defect density and production defect density have been improved significantly.
