Once you start using JIRA to track issues of any type, it becomes imperative to derive useful information from it. JIRA comes with built-in reports that show real-time statistics for projects, users, and other fields. At the time of running the project, reports will always display the most up-to-date information.
Let's take a look at each of these reports.
Open any project in JIRA that contains a lot of issues and has around 5 to 10 users, which are either assignees or reporters. When you open any project page, the default view is the summary view, which contains an Activity Stream that shows whatever is happening in the project, such as the creation of new issues, status updates, comments, and, basically, any change in the project.
On the left-hand side of the project summary page, there is a link for Reports under the project navigation sidebar. All the project-related reports can be found here.
