DevOps is about changing an organization's culture to prioritize collaboration between development and operations teams through automation and continuous delivery practices. It requires moving beyond simply purchasing new tools and instead focusing on operational design and breaking down silos between teams through culture change. While challenging, DevOps aims to help organizations streamline processes, treat infrastructure as automated and disposable, and deliver value to customers faster through practices like continuous integration and delivery.

“Most companies are built out of scar tissue”
“Scar tissue includes processes, rules, the HR manual, the whole
waterfall idea. Scar tissue prevents you from getting anything done.
