Part of this includes the whole concept of rushing a 'knocked together' MVP out there. It all depends on the product. Yeah, if you have an app to share cat pictures on a social network, then who cares if you have a flakey cobbled together app that doesn't upload half the time. The consequences are minimal.
If you have an app that is responsible for administering a life saving drug on a periodic basis, then you had better be sure the thing is polished, tested and reliable before even beginning to test it in the market.
The whole 'lean' system sausage factory is just that - creating a mass production line of ideas where only less than 1% float to the top. Very often only based on the fact that the creators shouted louder than others who may have had better (or more boring) ideas.
