Thank you, I think "good organization" would be one of those modern innovations most difficult to avoid, along with literacy, worker transportation, and abundance of fresh/clean food/water. Seems like they're trying to account for it though.
Good organization could be managed at tge time if one was powerful enough. I just checked Château Gaillard on Wikipedia, it's a typical medieval stronghold, quite advanced for its time. It was built in the exceptionnally short time 2 years along with the nearby town by Richard the Lionheart, with huge suns of money.
That's an impressive feat, but I imagine things like daily weather forecasts, copiers, and every worker having a pager/phone would have sped up production still. So much of modern day convenience allows organization far beyond what they could manage.
