One of the principles of the Agile Manifesto is "People over process". While that doesn't mean process is not important, it does mean people are more important. Whatever your process is, it should be focused on people, working code, customer collaboration and the ability to respond to changing requirements. Even if you try that, it's still possible to have a process that does these things badly. But I still have to see someone argue that these principles themselves are a bad idea. (Well, responding to change can be harmful when driven to extremes.)

Scrum is the most process-oriented process that's still pretty agile. But one of the most essential aspects of it is that you refine your process based on how it works. In an organization with multiple Scrum teams, eventually every team will have a slightly different way of doing things, because that's what works for them.
