I once insulted an employer with this expression :).
I told them that in the past we were building sheds, and that it all went very well. But now there was a skyskraper project, and that they cannot expect us to build that in the same way. I wanted to make clear that this bigger project needed more structure to support it.
All they heard was "what??? You think we build sheds???" :D.
Nothing wrong with building sheds of course. In fact those are the most fun projects.
And most developers don't understand that sometimes you want to build a shed. In that case, applying the skyscraper building conventions is overkill.
Of course building a skyscraper like a shed will never get you past the 4rth floor without the whole thing collapsing on you.
Also, at the end of a finite project, you can take some shortcuts to get things finished.
