Abstract

Software product line (SPL) engineering is an emerging paradigm for successful software reuse and has been adopted for various industrial and consumer products to improve their productivity and quality. However, most SPL methods require high initial costs and long development time, which makes many companies hesitate to adopt the SPL paradigm. In this paper we introduce a method to construct an SPL by extracting core assets from legacy components based on the feature model, which requires less initial time and effort. We also present a case study on cable set-top box software to illustrate the applicability of this method, and lessons learned that will provide guidelines for many companies to adopt the SPL paradigm.

산업 및 가전 제품에서 소프트웨어의 중요성이 커지면서 소프트웨어 재사용과 제품라인 방법론에 대한 관심이 높아지고 있다. 그러나 대부분의 제품라인 방법론은 초기 비용과 시간이 많이 들고 구체적인 절차나 성공 사례가 부족하여 산업체에서 적용하기에는 어려운 한계가 있다. 본 논문에서는 산업체에서 제품라인 기법을 쉽게 적용할 수 있도록, 기존에 개발된 소프트웨어 자산과 해당 도메인의 휘처모델을 활용하여 제품라인을 쉽게 구축할 수 있는 추출식 접근법의 구체적인 방법을 제시하고 이를 케이블 셋톱박스 소프트웨어에 적용한 사례를 소개한다. 또한, 제품라인으로의 전환 효과를 확인할 수 있는 평가 기준을 제안하고, 사례 연구를 통해 얻은 교훈을 정리하여 다른 산업 및 가전 제품의 소프트웨어에 적용할 수 있는 지침을 제공한다.
