If you want to see extremely toxic, combine this mentality from the business side with confirmation bias from developers who think the same way.

You get development efforts with massive scope people brush off as nothing. I've worked with a lot of these sort of groups where someone entrepreneurial understands enough to think they can simplify and improve something. Then they get a developer, two, or small team that agree. They start the undertaking or even worse, do the work under contract for someone else where they have contractual deliverables. Some way in they start to realize just how shortsighted and cavalier they were about brushing off uncertainties they either knew or didn't know about. "It can't be that hard! It's just software, it's all virtual! We don't need a bunch of capital! We just need a little bit of math! ... "

All those uncertainties start to become quantities and they realize the absolute pit they dug themselves into. At that point they look for someone to swoop in and cleanup their mess. Usually it takes careful reading of the contract deliverables with liberal interpretation of what is stated and how those things can be minimally met. You really need people familiar with the types of software and systems involved and needed to achieve your goals to narrow down these uncertainties. If you don't then you're digging your own grave.
