alt Hacker NewsIt's a good practice to run at 80% utilization and it helps if you are not being managed by people with an overseer mentality, who demand 100% from you all day, everyday. They are the ones who misinterpret the look of software engineers working in relaxed silent repose as lazy idleness. That's why remote work is the best thing to allow me to keep some utilization in reserve and to keep my sanity.
Doing a little bit of "glue work" can make you indispensable and also a hero to your team if it makes everyone's work life a whole lot better and no one else knows how to do it.
I'd argue 80% is high. This also varies between Devs. The way I learn, think about things, struggle to get started etc, means my 80% is no way near say, another colleagues' level who's simply stronger technically. Factor in any degree of NT tendency, and one person's 80 is anothers' 120.
