A bug not being tested fully, a developer working on a ticket that a PM didn't approve, a fix with no time logged... these are organizational problems. Yet the JIRA hammer lets you "fix" them by restricting workflow actions to certain users and making dozens of custom and required fields.

The result is a downward spiral: people avoid using it because it's painful and always getting in the way, which means no one puts extra effort in to link tickets together, write good descriptions/comments, or fill in non-required fields. The whole system becomes less useful overall, and in the worst case causing more workflow rules and required fields to be added.

It's sad, because JIRA can be good (though: slow). JQL is awesome if your tickets contain good data (after all, garbage-in garbage-out). It's very possible to have well formatted content that's easy to read. The "screens" customizations for transitions can make things faster by showing useful fields at just the right time. And the automations possible by integrating with PRs and builds can save even more time and prevent mistakes.

But all that can (and is) horribly abused to make something that is awful.
