In GSA IT, we examine how Agile and DevSecOps address different aspects of the delivery process. In terms of software development, Agile improves the process of delivery; encouraging changes in the functions and practices of the Business and Development teams to better produce the project / product envisioned by the end-user, or customer. In an ideal environment, an organization would employ both Agile or otherwise, but it is important to note that DevSec Ops can be implemented in any environment.”]
