EA (Enterprise Architecture) visualization methodologies have been explored by researchers and engineers to conduct EA modeling. The objectives of EA modeling are to clarify enterprise strategies, visualize business processes, and model information systems to manage resources, improve organization structure, adjust information strategy, and create new business value. Therefore, EA models can be broadly applied in various fields. For example, the applications include business modeling, information system architecture design, technology infrastructure configuration, software maintenance, and system security analysis. As the primary source of information, EA models are of paramount importance to researchers, architects, and developers. However, up to now, the purpose and means of these EA visualization methods have never been systematically analyzed and discussed, and a generalized EA visualization methodology with the ability to meet different demands is needed. The paper narrows this gap by conducting a systematic literature review on enterprise architecture visualization methodologies. In this study, 112 papers are retrieved by a manual search in 5 academic databases, a systematic literature review on EA visualization is explained to show a systematized category of visualization approaches, and then a general visualization approach is proposed by systematically reviewing the papers. Finally, the paper is concluded by discussing the contributions and limitations of the study.

Enterprise architecture (EA) is useful for promoting digital transformation in global companies and information societies. In this paper, the authors investigated and analyzed the process for digital transformation in global companies, together with related work in using and applying an enterprise architecture framework for the digital era named the adaptive integrated digital architecture framework (AIDAF). Moreover, they position the AIDAF framework for processing digital transformation in global companies. Based on this analysis, the authors propose and describe a new enterprise architecture process for promoting digital transformation in global companies. Furthermore, the authors propose an adaptive EA cycle-based architecture board framework on digital platforms, while verifying them with case studies in global companies. Finally, the authors clarify the challenges and critical success factors of the process and framework for digital transformation with architecture board reviews in the adaptive EA cycle to assist EA practitioners with its implementation.

Considering the relation between Enterprise Architecture (EA) and IT is a prerequisite when promoting the uptake of IT by societies. In this paper, the authors propose an “Adaptive Integrated EA framework,” based on the results of a survey, to support the strategy of promoting cloud/mobile IT. They considered a unique advanced case and provide details and the structure/mechanism of building this EA framework in a global pharmaceutical company. Moreover, the authors revealed the effectiveness of the proposed EA framework by evaluating/analyzing the problems caused by the rapid shift to cloud/mobile IT in divisions in the US and Europe. Furthermore, they compared the characteristics of The Open Group Architecture Framework (TOGAF) and the “Adaptive Integrated EA framework” (global deployment) in building EA frameworks while evaluating the effectiveness of this framework to achieve digital transformation. Finally, the authors clarify the challenges, benefits, and critical success factors of the framework to assist EA practitioners with its implementation.
