I mean, it makes a lot of money. But it's widely hated, and from what I've seen it's pretty bad at solving the problem it purports to solve. I guess some people call that success, but I wouldn't. My goals go beyond filling my pockets.
Of course, there are good managers of developers. But they neither use nor need Jira.
As an aside, I think that's why Agile and Lean methods have been mostly adopted in name only, leaving the substance untouched. The goal of both movements was to shift power to people doing the work, and managers see that as a reduction in importance.
