Enterprise architecture design using TOGAF at foundation of triputra persada horizon education

Abstract

The use of information technology in the field of education is currently a top priority for managing academic and supporting activities. Tri Putra Persada Horizon Education Foundation which manages two high schools, namely the College of Health Sciences and the College of Information and Computer Management should face a challenge to align business strategy with information technology, and how to integrate all the parts involved in the business and represent it in an information system. To find out the business strategy and governance of information technology used at the Tri Putra Persada Horizon Education Foundation, an Enterprises Architecture Framework is needed, one of which is TOGAF ADM. The Enterprises Architecture design contained in TOGAF ADM includes a vision architecture that defines the vision of the company or agency, a mapped business architecture in the form of value chain analysis, an information system architecture in which there is a data architecture and application architecture and the last is technology architecture. This research produced an enterprise architecture design blueprint consisting of artifacts, in the form of catalogues, matrices, and diagrams based on the phases of TOGAF ADM. The result of the Enterprise Architecture design was an integrated information system recommendation and the technology architecture. The design is expected to be a reference in improving the quality of business and is expected to make it easier to achieve the business goals of the Tri Putra Persada Horizon Education Foundation. 156 ILKOM Jurnal Ilmiah Vol. 13, No. 2, August 2021, pp. 155-162 E-ISSN 2548-7779 Purba, et. al.

Another research is the Application of The Open Group Architectural Framework (TOGAF) Model for Enterprise Architecture Design at STMIK Widya Pratama Pekalongan conducted by Rusli et al. [9], with the aim of realizing a good governance university. And research on Application Architecture Planning at the University of Lampung Using the Zachman Framework conducted by Novianti et al. [10], aimed to find the fact that changes in application requirements were the most dominant thing to be immediately repaired in each work unit. Based on the problem formulation, the purpose of the research is to produce an Enterprise Architecture design by determining a business framework using the TOGAF ADM method and to produce an information system architecture design consisting of data architecture, application architecture, information architecture and technology architecture. This enterprise architecture design was later used as a reference in the development of an integrated information system between STMIK and STIKes Kharisma Karawang. Method A. Architecture Architecture is a structured working relationship of a system consisting of hardware, software and network [11]. Architecture is also known as the basis of organizational systems that connect components in the system environment and have design and evaluation rules. The architecture in the discussion of enterprise-scale information systems is defined as the structure of components, the interrelationships, and the principles and guidelines for their design and evolution over time [12]. This understanding means that architecture is basically a picture of a company/institution/institutional structure consisting of various supporting components and the relationships between these components. B. Enterprise Architecture Enterprise Architecture is a framework or blueprint that serves as an organizational reference for achieving current and future business goals. Ways to achieve these business goals are by examining the keys to business success, information, application and technology governance and their impact on business functions. Each of these strategies is a separate architectural discipline and the function of Enterprise Architecture is the glue that integrates each discipline within a coherent framework as shown in Figure 1. Figure 1. Relationships between Architectures in EA [13] C. TOGAF ADM TOGAF ADM, as shown in Figure 2, is a suitable and credible method for developing enterprise IT architecture and business requirements. TOGAF ADM has the necessary stages in building an enterprise architecture [14]. Figure 2.

Preliminary Phase: is the stage used to determine the appropriate framework and scope of the organizational architecture. 2. 2. Architecture Vision: is the initial stage of the process of the importance of organizational architecture to achieve business goals formulated within the scope of the architecture to be developed. 3. 3. Business Architecture: this stage is used to enlarge the target and description of the current business architecture and will then be developed based on the findings of the analysis of current conditions. 4. 4. Information System Architecture: this stage prioritizes the development of the information system architecture. 5. 5. Technology Architecture: the stages are used to form the expected technological architectural design by taking into account all the procedures in selecting the required technology. D. Research Methods The steps taken in this research were: 1. Literature study Literature study aimed to see an overview of choosing the right framework architecture to be applied in the organization. 2. 2. Assessment The assessment consisted of two events, namely observation and interview. The observation aimed to see the first-hand conditions in the field on how the organizational architecture was applied. Interviews were conducted to obtain information from stakeholders and parts involved in the business process. 3. 3. TOGAF ADM Modeling We Modelled the findings into TOGAF ADM based on predetermined stages. Results and Discussion In conducting the business processes, Triputra Persada Horizon Education Foundation has implemented information technology as a commitment to become a quality university as stated in the explanation of VISION and MISSION. To maximize the implementation of the VISION and MISSION, it requires a well-developed enterprise architecture planning in accordance with the business strategy and development of educational institutions. TOGAF ADM was used as a method for modeling the existing architecture in the business process environment of the Triputra Persada Horizon Education Foundation. The stages in TOGAF ADM included: A. Preliminary: Framework and Principles This stage explained the need for defining the vision, mission, and goals to be achieved by the Triputra Persada Horizon Education Foundation which is divided into two parts, namely STMIK and STIKes Kharisma Karawang.
