Implementation of Information System Architecture Using TOGAF and Ward Peppard Analysis for High School

The development of IT has become a crucial and essential necessity for fostering innovation within companies. Recent technological advancements have resulted in Information Systems (IS) involving the processes of identification, evaluation, and decision-making related to a company's strategies. In its application, IS has been used not only within companies but has also extended into the realm of education. The significance of information systems in the education sector has become crucial for more modern education, especially in this era of education 4.0, where education tends toward digitalization. The high school is an educational organization located in Jakarta, Indonesia. These organizations have diverse business processes, ranging from the enrollment of new students, school data management such as student and teacher records, facility management, and the learning process, to routine divisional reporting, these high schools have not optimally and integratively implemented technology. They acknowledge the importance of integrating business processes with IS. Therefore, the design of enterprise architecture is needed to align business processes with information systems to ensure their mutual integration. The enterprise architecture undertaken in this study will assist in designing advancements in business processes, information systems, and organizational infrastructure, enabling high schools to better prepare for future challenges and move toward a more modern learning environment. This research employs The Open Group Architecture Framework (TOGAF ADM) combined with the application of the Ward Peppard method. TOGAF provides methods related to building, managing, and implementing enterprise architecture and information systems. The findings of this research consist of a blueprint recommendation comprising detailed proposals for integrated applications to enhance business processes and cater to the needs of the company. These recommendations can serve as a reference for designing information systems and making decisions in developing high school information systems.
