Role of Enterprise Architecture in Healthcare Organizations and Knowledge-Based Medical Diagnosis System

Abstract

Enterprise architecture (EA) is a tool that aligns organization's business-process with application and information technology (IT) through EAmodels. This EA model allows the organization to cut off unnecessary IT expenses and determines the future and current IT requirements and boosts organizational performance. Enterprise architecture may be employed in every firm where the firm or organization requires configurations between information technology and business functions. This research investigates the role of enterprise architecture in healthcare organizations and suggests the suitable EA framework for knowledge-based medical diagnostic system for EA modeling by comparing the two most widely used EA frameworks. The results of the comparison identified that the proposed EA has a better framework for knowledge-based medical diagnostic system.

Perancangan Enterprise Architecture pada Bidang Pelayanan Medis Menggunakan TOGAF ADM (Studi Kasus: Rumah Sakit XYZ)

“…Zachman Framework merupakan salah satu framework EA yang diperkenalkan oleh Zachman untuk mendokumentasikan arsitektur pada suatu organisasi dari berbagai sudut pandang dan menunjukkan relasi antar komponen pada perusahaan [11]. Framework ini menyediakan struktur logical dalam pengembangan, integrasi, perancangan, pengelolaan, dan akses sistem informasi perusahaan [12].…”

Towards Enterprise Technical Architecture for the Implementation of the South African NHI

“…The NHI implementation requires combination, co-existence, and integration of various IS/IT solutions, such as software, hardware platforms, network protocols, and databases towards achieving its goals [8]. Interoperability is of paramount importance as medical data and information would be shared among different entities [31]. This is not without architectural deployment.…”

“…As shown in Figure 1, the ETA is defined as a four phase approach, which are objective, development, implementation, and strategic [12]. The deployment of the ETA can on iteration basis address the integration and interoperability problems in health care systems [31]. Figure 1 is discussed, with focus on the cruciality of the ETA in the implementation of the NHI.…”

Enterprise Architecture Adoption for Higher Education Institutions

“…The findings demonstrated that EA adoption foster the alignment of IT and business goals in universities. Several studies have also highlighted EA adoption in the healthcare sector with important insights on how to implement similar EA in higher education [16] [17]. The overall conclusion from these studies is that every HEIs needs to focus on integrating the dimensions of people, processes, and technology [1].…”
