It can in the beginning seem like alot of micromanagement if you have a lot of planets and build facilities one at a time and then decides on what to build next(!)
What people tend to forget is that when the planets has built their facilities the micromanagement is mostly done there.
True, when new tech becomes availible you might need to scrap a few facilities and add new to the que, but these occasions are rare in the course of a long game.
