I noticed that there is a tag project-management. This should be explicitly off-topic and there is even a dedicated site for such questions, https://pm.stackexchange.com/. Notably, almost no question using the tag is actually about project management.
It's just 25 questions so I can clean this up myself with edits, but posting here before I go ahead. I'd do this according to the SO tag removal process which (TL;DR) basically means not just blindly removing the tag from every post, but also reviewing each post to see if it should be edited, closed or if other tags needs changing while at it. I trust that the same method is sensible to follow on EE as well.
