<![CDATA[Nufi Indonesia Tutoring Center still relies on manual operational processes, resulting in time and cost inefficiencies, difficulties in data management, and delays in information delivery. This study aims to design an Enterprise Architecture (EA) as a reference for developing an integrated information system using The Open Group Architecture Framework–Architecture Development Method (TOGAF-ADM). The research methodology covers the phases from Preliminary to Architecture Change Management, with requirements analysis using PIECES, Value Chain, and Gap Analysis. The results comprise an EA blueprint covering business process modeling using BPMN, application architecture design using Use Case Diagrams, data architecture using Class Diagrams, technology infrastructure, and a Migration Roadmap. Managerial validation showed that 63.64% of the assessments were categorized as appropriate, 18.18% as highly appropriate, and 18.18% as moderately appropriate. Therefore, the proposed EA design is considered suitable as a reference for developing an information system that meets the operational needs of Nufi Indonesia Tutoring Center.
