It can solve some project management issues for large scale teams. But it highly depends on how a company uses it. It is not mandatory to organize work though and I have only seen in companies you might not want to develop for.
Jira might be OK for me too. All the web products by Atlassian (Jira, bitbucket, and confluences we are using) are soooooooo slow from Japan. And it is the 80% of my hate. Is it not from US or somewhere?
