I wouldn’t underestimate the ability to iterate on fully finished features quickly, if you have to operate with end users. Closing a feedback loop can lead to threshold effects.
That'd be great if true. Human nature being what it is, chances are good that the ill thought out and in retrospect harmful will be deployed just as faster than "fully finished" as they are now.
Could that be iterated? Can a half baked release ever become whole or does progress just slow down and stretch out exponentially? 1/2 + 1/4 + 1/8 + ...
Yeah, I think my point is more that this makes it possible to iterate quicker while maintaining quality, which might be beneficial. Of course if you are working in a team that cares about the result (and the business does too), then iteration is always a win.
