Building a strong foundation for effective DevOps involves understanding key terms and concepts. Software development methodologies have been described throughout the history of computer engineering to improve the development and operations process. Many methodologies split work into phases with distinct activities, but they can lead to conflicting goals between development and operations teams. Forcing teams to follow specific methodologies can cause resentment and frustration if they don't align with their existing processes and goals. DevOps is not rigidly defined, and it does not prohibit any particular methodology. DevOps originated from advocating for Agile system administration and collaboration between development and operations teams.
