Internets of Things (IoT) applications and services have spread and are rapidly being deployed in the information services of the healthcare and financial industries, etc. However, the previous paper suggested that the current IoT services were individually developed, therefore, the open platform and architecture for the above IoT services of the healthcare industries should be deemed necessary. An open healthcare platform is expected to promote and implement the digital IT applications for healthcare communities efficiently. In this paper, we suggest that the open platform for healthcare related IoT services will be proposed and verified by the research initiative named “Open Healthcare Platform 2030 – OHP2030”. In addition, the vision for the OHP2030 research initiative is expressed.

A portal is expected to promote the creation of enterprise communication. In this paper, the communication process of the Architecture Board utilizing a global enterprise portal is analysed. On the basis of the results, a method for promoting the global enterprise portal is evaluated and proposed for the near future.

This study investigates the solutions incorporated by the Architecture Board in global healthcare enterprise (GHE) to mitigate architecture risks especially in Digital IT areas while proposing and implementing the Adaptive Integrated EA framework, which can be applied in companies promoting IT strategy with Cloud/Mobile IT. The study revealed the distribution of solutions across the architecture domains in Enterprise Architecture covering applications and technologies with Cloud/Mobile IT/Digital IT to mitigate risks. An in-depth analysis of this distribution resulted in practical guidance for companies that consider Risk Management for Digital Transformation while starting up the Architecture Board in Enterprise Architecture with IT strategy covering Digital IT related elements.

This study proposes a visualization method for service ideas by considering the usage context based on various stakeholders’ experiences gained in tabletop fieldwork. The proposed method is characterized by “idea generation through making combinations” as well as “experience-sharing based on tabletop fieldwork”. We applied the proposed method to two workshops, and confirmed that a total of 118 people successfully visualized their ideas in a short time using the proposed method. This study details the procedure of visualization, and shows that the proposed method assists in developing master plans and future visions.

Since the year 2000, Enterprise Architecture has been the object of focus as a method for promoting an IT architecture that establishes consistency between corporate business and IT strategies, and it has been applied mostly in global corporations. On the other hand, with the recent progress in Mobile IT technology and Cloud computing, in the IT systems of global corporations, the shift from conventional on premise server-based IT systems to Cloud computing, such as Software as a Service (SaaS), Hybrid Cloud, and connected Mobile IT systems, has become more pronounced. In promoting Enterprise Architecture, EA based upon an approach compatible to the cutting-edge IT technologies of Mobile IT/Cloud computing will be required by global corporations. This paper elucidates key points for EA methods to respond to the cutting-edge IT technology that will be required in the future by conducting a comparative analysis of the support environments of Mobile IT elements and related Cloud computing technology in each EA framework currently used widely in many global corporations.
