“Highly effective, daily collaboration between software developers and IT operations people to produce relevant, working systems.”, Matthew Skelton
“DevOps means a culture where developers
and web operations engineers communicate
and work together, as opposed to a siloed
organisation where developers throw code
over the wall to operations and expect web
operations engineers to make sure it runs in
production”, Anna Shipman
“I’m afraid I’m a tester…so have pretty much no
idea what DevOps was about.”, Amy Phillips

“DevOps is about developers and operations
people working collaboratively to release software to users.”, Dave Farley
“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.”,
