What is the most accurate definition of DevOps?

DevOps is defined within the SAFe framework as a mindset, a culture, and a set of technical practices. It is not just a set of tools or a single process, but rather a combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity. This definition aligns with option C, which emphasizes the importance of close cooperation between development and operations teams to provide value to the customer. The SAFe framework further elaborates that DevOps is part of the Agile Product Delivery competency and is essential for a Continuous Delivery Pipeline (CDP). It helps break down organizational silos and enables the fast flow of planned work into production, while achieving stability, reliability, availability, and security. The goal of DevOps is to deliver value whenever there is a business need, and it is supported by the CALMR approach—Culture, Automation, Lean-flow, Measurement, and Recovery—which guides the implementation of DevOps in a SAFe enterprise1.
