Micromanagement, depending on what it means, can be a valuable tool in fixing a broken system. e.g. you take over a team where everything's broken and shipping late. It can genuinely be very helpful for you to dive into the details of everybody's tasks and figure out where things are breaking down. You get a detailed look at the bottlenecks that senior people face (but may be reluctant to share for political/personal reasons); and you get a detailed look at the knowledge/skills gaps that hinder juniors.

It's not sustainable though. The idea is to dive in, figure out what to fix, then fix it into a system you can stop micromanaging. Otherwise you just won't have enough time to do the other important stuff.
