As almost everyone knows, construction delays and cost overruns are the norm, not the outlyer. Construction projects here very often suffer dearly from the "2 more weeks and/or a couple more thousand dollars" overrun issues.
In fact, I'm sure at least several people who have been trapped in a home renovation nightmare LOLed deeply after reading your post.
These stories are SO common (and I've seen it in my own family too) that I truly question the sanity of anyone who takes on a home renovation project.
Houses (not housing tracts) tend to be built by much smaller contractors who are in absolutely no position to absorb any setback without going bankrupt, you can't apply the rules for 'big business' to small time operators and expect the exact same outcome.
Constructing resorts also has all kinds of economies of scale that building individual houses does not.
This is very doable in software, and I’ve seen it done for decades from all levels of the org chart.
