My favourite personal example of this was a "big project" I was working on in the early 2000's. There were two QA reviewers for my project plan: One raised "serious objections" to the QA section, saying it wasn't detailed enough, we needed a full test plan, and demanding TDD be used for all development. They cc'ed the CEO with their review. The second QA reviewer said the test plan was a "good high level approach" and that only thing they wanted to see was an explicit "design for testability" requirement for one of the critical, and hairy, modules.
