Large orgs/enterprises aren't about solving the problem - it's about the ceremony around solving the problem expecting the problem to solve itself eventually. Going around that ceremony can/will be seen as "going rogue" and will often end in termination of some sort. If the company wants/needs someone outside of that ceremony they will likely go "hire a consultant" vs. trying to find solutions within the ranks.
I'm not supporting this - I'm just saying it's how it is at the majority of larger companies that I've worked for/with. Honestly I think it sucks and stands in the way of real problem solving.
