There are many good systems for doing the bug report tickets. Good open source tools. Some people like HP-Quality-Center. But most developer teams seem to like Jira, because it is easy to use, has hosting options and good functionality and stability. Also there are ways to support modern agile development styles like Kanban and Scrum. And it comes with a nice Wiki that apparently has partly or fully replaced Word documents in most projects that I have seen over the last 10 years.
Please remember, it is pronounced [ˈdʒi.rɑː] and not [ˈdʒɑi.rɑː]. For English speakers: think of „Jeera“. For German speakers: think of „Djihra“. The word is of Japanese origin and usually it does not work to apply an assumed English pronunciation to any non-English language. English is too irregular to guess the pronunciation without knowing the word for most of us. And more irregular than most other languages.
