Abstract

The development process of Embedded Software (SW) is gathering interest due to the increased importance of SW in mobile products. According to tough competition and the growing size of the Embedded SW, there is a demand for a new effective way to improve the SW development process, based on customer and market quality aspects, rather than focusing on defect removals in individual SW modules. We review 103 SW improvement projects from the area of mobile phones in order to check the effectiveness of Six Sigma which is the standard for the process improvement statistical tools and methods.

모바일 제품에서 임베디드 소프트웨어(Embedded Software)의 역할이 중요해짐에 따라 소프트웨어(SW) 개발 프로세스에 대한 관심이 높아지고 있다. 또한 모바일 제품 시장에서 기업 간의 경쟁이 치열해 지고 적용되는 SW의 규모가 커짐에 따라 SW 개별 모듈의 결함 관리보다는 고객 사용 환경과 시장 품질의 관점에서 SW 개발 프로세스를 개선할 수 있는 새로운 방법이 요구되고 있다. 이 논문에서는 모바일 폰 분야에서 실행된 103개의 SW 개선 프로젝트를 검토하여 프로세스 개선 방법으로 자리 잡고 있는 식스 시그마 방법의 SW 분야 적용 가능성과 통계적 도구와 방법의 유용성을 확인해 보고자 한다.
