<![CDATA[Although the coffee shop sector continues to expand quickly, enterprise architecture research in this domain has generally treated the customer-facing point of sale and the upstream sourcing of coffee as two separate concerns, so that supply chain and customer interaction are rarely represented together. This study builds an integrated enterprise architecture model for a coffee shop enterprise that brings supply chain operations and customer interaction into a single design spanning three product lines: coffee beverage, non-coffee beverage, and food and snack sales. The study is conceptual and design-oriented; the enterprise modelled is a representative reference case reconstructed from operational patterns reported in earlier studies of independent coffee shops, not an empirically observed firm. The work follows the phases of The Open Group Architecture Framework Architecture Development Method, from the Preliminary Phase to Migration Planning, with ArchiMate as the modelling notation and the Business Model Canvas as the expression of the business logic. The findings show that the Architecture Vision phase connects three stakeholder groups and their strategic drivers to specific realizing components, namely integrated point-of-sale management, customer service management, and smart inventory management, while the Business Architecture phase shows that all three product lines share a recurring procurement-inventory-preparation-sales pattern and rely on a common supplier and point-of-sale application layer instead of separate systems. A preliminary analytical self-assessment of coverage and traceability indicates internal completeness, whereas expert validation remains future work. The model offers a reusable reference architecture for the digital transformation of small and medium coffee shop enterprises.]]>
