Purpose: Challenges associated with changes in the last ten years confirmed the importance of businesses' use of the software. Today, organizations are viewed differently by the cost and quality of software. While the organizations formally reduce redundant development and engineering costs, the fundamental nature of the software in a product or service on the evaluation is a development process. Thus, organizations are looking for effective software development.
Methodology: In this study, Six Sigma methodology focuses on improving the process and reducing variability. Six Sigma projects use one of two DMAIC and DFSS methodologies.
Findings: Two dominant approaches are available if they are participating. One of the solutions is the CMMI model, which is a framework for improving the methods and service delivery. Another option is to use the Six Sigma program to articulate the issues of quality and customer satisfaction. It is necessary to understand whether these attitudes are compatible with integrated systems or should be used independently.
Originality/Value: This paper addresses the issues of coherence and consistency of these two methodologies and checks their coherence strategies.
