Exploring Innovation Model and Evolution of Medical Cloud Service: A Case Study of Chung-Hwa Telecom in Taiwan

[[abstract]]"This study is a case study of Chung-Hwa Telecom. Based on a framework of cloud service, this study develops an innovation model of medical cloud services (MCS) and explores the evolution of the model. Through collecting the related secondary data of the case from 2002 to 2011 and in-depth interviews, this study has collected 274 events of service innovation. Each event is treated as an analysis unit. The findings are: 1) MCS innovations focus on CaaS, IaaS and PaaS, while SaaS and DaaS are insufficient; 2) MCS innovation evolution is from PaaS to IaaS; 3) The critical factors facilitating MCS concern infrastructure technology and network technology; 4) The quantity of both general and enterprise users served by MCS shows a U-type trend; the quantity of both government institutions and specific communities served by MCS shows an inverted U-type trend; the quantity of both education institutions and medical institutions served by MCS shows an increasing trend.
