It’s easy to be bad and hard to be good. There’s PMs I know that casually joke about how about most of their week is time spent dicking around on the internet while having a few meetings and watching some tasks get done. They are more like project secretaries where they DGAF about being involved. Then there are PMs that go the extra mile to keep stakeholders involved, triage bugs and tasks, and willfully volunteer to fill in as needed. They are the ones that can actually add substantial value to a project.
