Gregory Kneller, whom I have enjoyed working with on various things regarding JIRA time tracking with Worklog Assistant, presented a case-study with Atlassian about using JIRA for solving general business problems.

Among the things considered:

• Sharing documents
  
• Time tracking
  
• Dashboards

One of the things I found most interesting was how Gregory managed to make JIRA match the nomenclature of the domain in which he was working. For example, "Issues" became "Projects". Another very interesting aspect was his presentation of worklogs as a "ship log" or a kind of journal. I also use worklogs in the same manner and I'm happy to see that others do as well!

I'm not sure if the slides are available for a quick review, but I'd recommend even a quick run-through of the video. You might get some new ideas.
