Nope, they never do.

That's how you end up with those cooking recipes that only "take 5 minutes". Sure, if you don't count buying all the ingredients, cleaning and preparing them, cleaning up the pots and pans (and probably the worktop, stove, etc), a lot of things can take 5 minutes. Even trivial stuff like scrambled eggs don't actually take 5 minutes when you take everything into account.

Reminds me when I automated a manual service deployment that only "took 5 minutes". Sure, copying the binaries only took 5 minutes, but coordinating between various departments to deactivate the relevant monitoring bits, turning off the services, invalidate the caches, etc, etc actually took half a day with humans involved. Once automated and parallelized the thing took about 10 minutes for a data center.
