Abstract

This article aims to investigate solutions incorporated by a group called an Architecture Board in the global healthcare enterprises (GHE) for solving issues and mitigating related architecture risks while implementing “Adaptive Integrated EA framework,” which can be applied in companies promoting IT strategy using Cloud/Mobile IT. The distribution of solutions is to mitigate risks from different categories across the architecture domains in enterprise architecture (EA) is revealed, thereby covering applications, involving ERP, and technologies using the Cloud/Mobile IT/Digital IT. An in-depth analysis of this distribution can act as practical guidance for companies that consider starting up an Architecture Board, by utilizing digital platforms, while moving toward a digital transformation in an adaptive EA aligned with an IT strategy, encompassing digital IT-related elements.

2. Direction Of Ea

In the past 10 years, EA has become an important method for modeling the relationship between the overall image of corporate and individual systems. In ISO/IEC/IEEE42010:2011, an architecture framework is defined as “conventions, principles, and practices for the description of architecture established within a specific domain of application and/or community of stakeholders.” In addition, EA visualizes the current corporate IT environment and business landscape to promote a desirable future IT model (Buckl et al., 2010). EA is an essential element of corporate IT planning and offers benefits to companies, such as coordination between business and IT, enhancement in organizational communication, and reduction in the complexity of IT (Tamm et al., 2011).

In general, Mobile IT computing is an emerging concept that uses Cloud services provided over mobile devices (Muhammad and Khan, 2015). Mobile IT applications are composed of Web services. Few studies discussed EA integration with Mobile IT, however, integration with service-oriented architecture (SOA) has been discussed, that several organizations have invested in as a crucial approach to manage rapid change (Chen et al., 2010). Meanwhile, attention has been focused on microservice architecture recently, which allows rapid adoption of new technologies such as Mobile IT applications and Cloud computing (Newman, 2015).
