> Also, that the product is 10% better/more stable/whatever frequently does not translate into even a 10% increase in sales. So it's not worth it (from the business' perspective) to invest in that quality.

Here is the core of the problem, and it's more of an incompatibility of goals than errors of one of the parties. Businesses want to make money. They usually don't give a flying fuck about what their product is or does beyond the point it gets sold. Does it waste users' time and piss them off? They paid us, which means they value it, so everything is ok.

Engineers, on the other hand, tend to care about what value the product actually provides to their users. So they would rather invest effort in making the product better for the users, instead of making it better for sales team to sell.

I don't really see the way out of this conflict. The engineers are right, but the businesses are right too - it's the business that pays and suffers (some of) the consequences, so it's the business that gets to tell engineers what to do, and not the other way around. If CEO is making a stupid decision, that's on CEO.

The way I see actually useful software gets done, it's outside or on the side of a business, not within it.
