> With all due respect, if the idea is good, then it will happen

Working in a corporate environment, I have not found this to be the case. Good ideas get nowhere without buy-in

I think it really depends on the motivations of the business. Some are more R&D and innovation driven. Getting "buy-in" is technically necessary, but trivially easy as long as the biggest cost is only development time. If it's a bad idea, it eventually fades away as other priorities take over.

There is no one singular "corporate environment". This is especially true when a lot of people working there tend to not job hop much. Time both grows that particular work culture, and keeps those people ignorant.
