The use of information technology has become important to assist data processing, especially in the electrical equipment retail industry. Retail industry technology has not been fully utilized, especially in terms of marketing, production, delivery, finance and human resources. Problems that arise, such as long data processing times, miscalculation of financial invoices and many more. To harmonize business processes and information systems, business architecture and information systems are designed using the Open Group Architecture Framework (TOGAF) standard with the Architecture Development Method (ADM) method. The selection of TOGAF ADM aims to explain the architecture of the retail industry more specifically in terms of business, technology and information. This research phase includes preliminary, information technology strategy identification, solution identification, architectural vision and enterprise architecture. This research produces an enterprise architecture blueprint design in the form of proposed applications from the business, information and technology side, which is only limited to design. The implementation of the TOGAF ADM phase can maximize the retail industry's business processes in terms of concepts, techniques, integration between business and information technology and determine the transformation in all business, data, application and technology domains.
