However, software by itself is prone to errors and bugs leading to disastrous results at times. This has caused many software agencies to look for standardized software engineering processes which result in increased reliability, less debugging and improved quality control. Six Sigma has taken the manufacturing world by storm with its proven results in increasing quality and reducing defects. It is therefore natural that in the past few years, software corporations and firms are now looking to see how Six Sigma methods can be incorporated into the software engineering process. Many companies have tried and successfully implemented Six Sigma methods in the software development , design and testing processes in Software Engineering. However there is still a lot of skepticism wi”
