Abstract

This study aims to analyze the causes of a new product failure by using system safety methods, focusing on the case of Samsung Galaxy Note7. However, when analyzing the causes of a product failure, if only technical problems are too emphasized, it is likely to miss other more meaningful causes of a failure. Thus, we claim that the root causes of a product failure should be identified in a broad perspective of integrated systems that include non-technical as well as technical elements. With this viewpoint, we investigated the failure of Samsung Galaxy Note7, by using Root Cause Analysis(RCA) and Fault Tree Analysis (FTA). The results showed that it is necessary to address not only the technical issues but also other non-technical issues, such as a very impetuous launch of a new product due to a very tough competition in the market. Additionally, we also found that RCA and FTA could be a useful tool for analyzing the causes of a new product failure from the viewpoint of an integrated system comprising technical and management elements.

본 연구의 목적은 갤럭시노트7의 예를 들어 신제품의 실패를 시스템 안전분석 기법을 활용해 체계적으로 분석하는 것이다. 이러한 분석을 통해 제품실패의 근본적인 원인을 찾고 그 원인으로 발생하는 문제를 해결함으로써 사건재발을 방지하는데 도움이 되는 정보를 제공하고자 한다. 이를 위해 제품실패를 단순히 기술적 실패로 바라보는 것이 아니라 제품개발과 경영관리가 포함된 하나의 통합 시스템으로 바라보며, 그에 대한 실패의 근본적인 원인들을 분석할 필요가 있다. 이러한 관점을 갖고 시스템 안전분석 기법인 근본원인분석과 고장수목분석을 활용해 갤럭시노트7의 제품실패 원인을 분석하였다. 이러한 분석과정을 통해 배터리 과열이라는 피상적인 기술적 문제와 더불어 경쟁사와의 지나친 경쟁에 따른 무리한 제품출시와 성과주의와 같은 제품개발 및 경영관리에서의 문제에도 많은 관심을 기울일 필요가 있음을 파악하였다. 또한 통합 시스템적 관점을 견지한다면 제품실패의 원인을 분석하는데 근본원인분석과 고장수목분석이 유용하게 이용될 수 있음을 확인할 수 있었다.
