I think you underestimate inefficiency of requiring all business analysts and employees to learn GIT. If not all employees than more employees. I can pick put up job ad for BA saying knows JIRA and I have dozens of applicants.
We had a technical guy once where I worked that wanted to force sales guys to use LaTex to write documentation and requirements in and store it in GIT. I feel bad for the guy as he was laughed out by sales guys and he did not understood why because those are such a great tools…
Yes, but isn't it insane? What is the benefit from treating your own product as a black box? Yet that's mainstream. Sometimes I have the analyst (not on my team, but from a team we share a monorepo with) asking me questions that can be answered literally with a line of code. And she's a technical kind, knows SQL and such. And we write very idiomatic, high level code. But still, culture cannot change itself until it dies due to inherent inefficiency.
