I think the difference between the best practices for "lean startups" vs "enterprise" is overstated. The benefits of fast feedback still apply to large projects - the only real difference is that big companies won't necessarily die from inefficiencies like over engineering. And the fact that, over anything but a very short timeframe, the right way is also the fastest way still applies to startups. Sometimes a shortcut is in order - but you can't sustain that for as long as it will usually take to become established. Real experience teaches you how to choose the right balance.
