Service-Oriented Architecture (SOA) is a way of organizing systems to improve service delivery. Researchers reviewed studies on SOA from 2009 to 2019 to understand its success and failures. They found that factors like governance, strategy, costs, and training are crucial for successful adoption and implementation of SOA. Most recent research focuses on practical aspects of SOA, like how it is used in real-world settings. This information can help professionals and researchers better understand and implement SOA in their organizations.
