Since the beginning of information technology, organizations have experienced a permanent increase in the dimension and complexity of business information systems. Architectures are typically used in the information technology domain to build plans for a company, organize and optimize system components, interfaces, processes and business capabilities, among others. An enterprise architecture framework establishes a practical guide for analyzing, understanding, and applying technical descriptions of an architecture in a particular business area. Designing and / or adapting an appropriate enterprise architecture framework has been one of the challenges in recent years for many companies, especially for SMEs. This article has the objective of compiling and investigating which are the main Enterprise Architecture Frameworks and which are the factors that influence SMEs when adopting an enterprise architecture framework. After reviewing the literature, we have found one hundred thirteen articles and selected twenty-five of them according to the inclusion and exclusion criteria defined in this research. As a result of this article, we have identified twenty enterprise architecture models based on three enterprise architecture frameworks and seven factors that influence SMEs when adopting an enterprise architecture.
