The software industry is facing many problems due to the inefficiency of methods or tools for process improvement, resulting in cost overruns in software engineering. The quality of the software becomes difficult to control; maintenance costs are high and system replacement is difficult. To overcome these problems, this paper introduces the Design for Six Sigma (DFSS) into the software requirement process. It analyzes the existing problems foundation of requirement engineering process, transforms existing processes and proposes the requirement engineering process model based on DFSS. Based on DFSS methods and techniques, the model combines the IDDOV (Identity, Define, Develop, Optimize, Verify) process with the practical situation of software requirements engineering process. It emphasizes the importance of software quality and their integration into the acquisition of various stages of quality characteristics. Quality Function Deployment (QFD) and Failure Mode And Effects Analysis (FMEA) are applied to insure customer requirements are adequately transformed into design requirements. At the same time the study explores the potential requirements and failure risks in order to improve the efficiency of software system development. In summary, the DFSS approach provided the software industry with structured process improvement strategy to reduce non-value adding activities and other problems.
