Thanks for clarifying! I also really liked the SRM process.

Insomuch as people protecting their jobs: that's always a thing. But I honestly felt that people wanted to protect their jobs because they wanted to protect the public. Some people definitely wanted to keep their work and personal life separate with solid 9-to-5 boundaries. That's perfectly OK too. It was helpful to be inclusive of them even if their time was already filled.

I worked with numerous people who didn't understand all of the components or systems. We took it upon ourselves to be very open to questions and to thoroughly explain how each thing works. I've found if someone had good understanding of one component but didn't understand another component, it was very useful to schedule time with them to walk through the components they didn't understand to try to alleviate their concerns. They might not know what questions to ask, so I would instead ask questions about their well-known components to try to understand and correlate to newer components. Perhaps their concerns were even justified but they didn't know how to articulate them!
