Abstract
We have enhanced ERVM (Earned Requirement Value Method) and studied a quality control model from the viewpoint of QFD-based traceability of system requirements. The study is aimed at getting the product of good quality in the requirement analysis and design phases of embedded software. One of the serious problems is the quality of requirement analysis and design in the field of embedded software development projects. Therefore, it is inevitable to get the good quality in the requirement analysis and design phases. If the good quality is not obtained in the requirement analysis and design phases, the project will easily fail by the rework in the implement phase and the malfunction in the operation. In this paper, we discuss the model and describe the future study.
