This document discusses the reasons for adopting a DevOps approach and culture. It outlines how the business and technical environment has changed with factors like Agile development, cloud computing, and shadow IT. These changes have increased pressure on operations teams and created a need for new IT models. DevOps is presented as a solution that can help organizations deliver business value across the product lifecycle through practices like automation, collaboration, and metrics. The document advocates for adopting a DevOps culture and model to help organizations react to changes and gain competitive advantages like reduced lead time.

3. “It's a movement of people who think it's time for
change in the IT industry - time to stop wasting
money, time to start delivering great software, and
building systems that scale and last.”

A little bit of DevOps WHAT, first 3

4. DevOps is an alternative model for the creation of
business value from the software development life-
cycle that encompasses a product-centric view
across the entire product life-cycle (from inception
to retirement) and recognises the value in close
collaboration, experimentation and rapid
feedback.”
