The Federal Enterprise Architecture Framework (FEAF) is a structured approach used by the U.S. federal government to improve the efficiency and effectiveness of its operations. It provides a common framework for agencies to align their IT investments with their business goals, ensuring that resources are used effectively and that services are delivered efficiently. FEAF consists of several components, including reference models that guide agencies in developing their enterprise architectures. These models help in standardizing processes and promoting interoperability among different government systems, ultimately enhancing collaboration and service delivery across federal agencies.
