Funny I find jira to be very useful for a nice centralized location of where we keep issues that weve come across and will, at some point, handle, but are not going to get to now.
Other than our team lead, I don't think any of our managers even look at it.
I guess we just use a very stripped down version of jira, because it's really just enter an issue, brief explanation, and further documentation to help whoever comes to fix it solve it faster. If it takes me longer than 5 minutes to create a ticket that means I've spent way longer than usual.
I think of it as a good place to keep a record of know issues or desired improvements, so they don't get forgotten.
