So, Dupe Stats/Skills - Do they only impact speed of jobs?

I'm curious because so far I think this is the only thing I'm seeing. For all the various skills, is there any other impact to what they do except increasing speed (or amount of weight carried around?)

Taking the Build skill as an example. Does it effect in any way the quality of what is being built? Or any other aspect ?

My first runs with the game, I would try to get a dupe with high construction stats and then only use him as a builder. But unlike other games of the genre, the construction stat only seems to affect speed. So in the end I found it was more efficient to just set everybody to build (save some exceptions like the cook). Everything got built faster and over time, the dupes all got better/faster.

Same applies to cooking, and also medicine.

Was wondering if I was missing something. At first I thought a better builder or cook would produce better quality things/meals, but I'm not seeing it.
