There’s also personal aspect to that: working when your mind already fails - sucks. It feels like wandering in a deep forest only occasionally seeing the light. Or clicking randomly through windows management consoles in hope it works. Very uncomfortable, boring and demotivating, even if nothing goes wrong in a project afterwards.

This probably has no economical benefit even. I believe in most cases a second shift would do this work much quicker than an exhausted team that spends most of this time squeezing last drops of sanity at overtime rate. [laughs in corporative]
