The Six Sigma methodology consisting of the following stepsdefine, measure, analyze, improve, and control. Within this improvement framework, it is the responsibility of the improvement team to identify the process, the definition of a defect, and the corresponding measurements. This degree of flexibility enables the Six Sigma method, along with its toolkit, to easily integrate with existing models of software process implementation.Six Sigma is a well-liked method to make changeability from developments by means of prevailing statistical instruments and skills (12). Although originally introduced by Motorola in 1986 as a quality performance measurement, six sigma has evolved into a statistically oriented approach to process and product quality improvement. Many organizations have reported significant benefits as a result of six sigma project implementation, though not all are yet success stories.The notion of execution of the Six Sigma approach was initiated at Motorola in the 1980s with the objective of decreasing value rates and rates of not accomplishing things right the first time, rates of not beating consumer’s needs. After Motorola, other companies such as Texas Instruments, Allied Signal, Kodak, General Electric, Sony, etc. have claimed great savings as a result of the implementation of Six Sigma projects. However, Six Sigma stresses the application of statistical and problem-solving tools and techniques in a methodical and systematic fashion to gain knowledge that leads to breakthrough improvements with a dramatic impact on the bottom-line results. While the original goal of Six Sigma was to focus on the manufacturing process, today, marketing, purchasing, billing, and invoicing functions are also embarked on Six Sigma strategies with the aim of continuously reducing defects throughout the organization’s processes.The main factors that are indispensable to the accomplishment of the execution of any excellence development inventiveness.
