DevOps started in 2009. This paradigm shift enables many organizations to accelerate the rate of software delivery and business performance as demonstrated in the Accelerate report and its well-known DORA metrics of speed, stability, and recovery.
Agile was the first popular combination with DevOps to equilibrate business value and technology delivery on the same flow of work.
More recent practices such as reliability or security embrace the same mindset coining terms of “SRE” and “DevSecOps”.
