Doesn't this ignore the glaring difference between a plumbing task and a software task? That is, level of uncertainty and specification. I'm sure there are some, but I can't think of any ambiguous plumbing requirements on the level of what is typical from the median software shop.

Sorry, I edited the plumbing refence out of my comment because I saw a sibling post that made a similar point.

I agree there is less uncertainty in plumbing - but not none. My brother runs a plumbing company and they do lose money on jobs sometimes, even with considerable margin. Also when I've needed to get n quotes, the variation was usually considerable.

I think one big situational difference is that my brother is to some extent "on the hook" for quotes (variations / exclusions / assumptions aside) and the consequences are fairly direct.

Whereas as an employee giving an estimate to another department, hey you do your best but there are realistically zero consequences for being wrong. Like maybe there is some reputational cost? But either me or that manager is likely to be gone in a few years, and anyway, it's all the company's money...
