Oh my god thank you. Software engineering seems to be the only field where it seems like these types of super weird arguments about being too special or unique to follow or apply any business process are common, coupled with a vibe of "we are way smarter than everyone else".

Why are these people surprised that other stakeholders won't just accept a "trust me bro, it's ready when it's ready you just have to go with it" when nothing else works like that in the business world.
