Abstract

Internet of Things (IoT) is considered to be the next wave of Information Technology transformation after the Internet has changed the process of doing business. Since the domain of IoT ranging from the sensor technology to service to the users is wide, the structure of the research domain is not delineated clearly. To do that we suggest to use the Technology Stack Model proposed by Porter et al.(2014) to measure the maturity level of IoT in organizations. Based on the Stack Model, for the general understandings of IoT, we do keyword analyses on the academic papers whose major research issue is IoT. It is found that the current status of IoT application from the perspectives of cloud and big data analytics is not active, meaning that the real value of IoT has not been realized. We also examine the cases which deal with the part of cloud process which is crucial for value accrual. Based on these findings, we suggest the future direction of IoT research. We also propose that IT is to value chain what IoT is to the Stack Model to derive value in organizations.

사물인터넷은 인터넷이 비즈니스 프로세스를 근본적으로 변화시킨 이후의 기술로 간주되고 있다. 그러나 사물인터넷의 영역이 하드웨어적인 센서 기술로부터 애플리케이션을 통한 서비스까지 광범위하여 아직까지 연구도메인에 대한 구조가 명확하지 않다. 본 연구에서는 기업에 가치를 제공하기 위해서 사물인터넷의 성숙도를 측정하기 위하여 Porter 등 (2014)이 제안한 기술스택 모델을 적용할 것을 제안한다. 스택모델을 이용하여 사회과학, 복합학, 공학 분야에서 발간되는 논문을 대상으로, "사물인터넷(IoT)"을 키워드로 포함하고 있는 논문의 저자들이 제공한 키워드 분석을 실시하여 사물인터넷 연구의 일반적인 동향을 살펴본다. 결과에 의하면, 클라우드와 빅데이터 분석 기반의 IoT 활용은 활발하지 못하고 결과적으로 IoT로부터의 가치가 충분히 실현되지 못하는 것으로 나타났다. 또한 가치 도출에 중요한 클라우드 프로세스를 적용하는 연구 논문 사례를 발췌하여 사물인터넷의 응용 수준을 측정하였다. 본 연구에서 IT의 가치사슬모형 적용과 유사하게, IoT의 가치를 높이기 위해 스택모델 적용을 제안한 것도 의미가 있다 할 수 있다.
