Abstract
This article provides a systematic review of the Enterprise Architecture (EA) adoption model. Firstly, an analysis of the literature discussing the current EA adoption models was undertaken. The EA adoption models were reviewed to identify which adoption phase can be connected. This paper also discusses the limitations of the models. Based on the inclusion and exclusion criteria defined in the review process, 13 articles were reviewed. There are 13 different EA adoption models across the number of adoption phases which were selected from 13 articles. A total of 11 adoption models were designed for the post-adoption phase and applicable for the EA implementation phase and two (2) adoption models were formulated for adoption phase. This SLR reflected that there was relatively little research conducted in the adoption phase. Previous scholars had adopted one or a combination of different underpinning theories in their studies to identify the existing approach and perspective formulating EA adoption model. The finding also revealed the limitation of previous studies such as generalizability and fragmented perspective. Therefore, this review will provide further investigation into the potential development of EA adoption model at an early stage that could provide wide-ranging and rational views of business, information, and technology for the organisation.
Highlights
Enterprise Architecture (EA) imparts a holistic outlook of organisational business strategies, Information Technology (IT) initiatives as well as the supporting environments to accomplish organisational goals to support organisation efficiency and effectiveness
This review has identified that the number of studies in this area is increasing from the year 2010
It is obvious that there is an absence of EA adoption models during the adoption phase and early process of establishing the EA
Summary
Enterprise Architecture (EA) imparts a holistic outlook of organisational business strategies, Information Technology (IT) initiatives as well as the supporting environments to accomplish organisational goals to support organisation efficiency and effectiveness. Enterprise Architecture is a time-sensitive process that requires an agreement between business and IT people for gaining mutual understanding and decision. This agreement requires a long-term commitment and maintenance over time. The lack of study in EA at the early stage of pre-adoption and adoption may cause resistance to change and poor decision-making. This drives for further investigation of EA adoption model at an early stage of adoption. The remainder of the paper is organized as follows; literature review, review method, results and discussion, and conclusion
