Technology is rapidly evolving in modern society. A key solution for organizations to keep up with the development of technology and retain market share is to implement EA. Organizations use Enterprise Architecture (EA) to stay competitive by aligning IT with business goals. This study aimed to identify which EA-modeling notations are used in practice, focusing on how choices relate to industry, implementation year, and organizational size. A global survey with 40 EA professionals was conducted using a quantitative approach. The most commonly used modeling notations were Archimate, Business Process Modeling Notation (BPMN), and Unified Modeling Language (UML). Statistical analysis through Pearson’s Correlation test showed no significant correlation between modeling notation and industry, EA implementation year, or organizational size. However, it was noticeable that people within the public sector often used BPMN and Business Model Canvas (BMC). Furthermore, all organizations surveyed had implemented EA after 2000, and most were large companies with over 250 employees.
