This report charts the number of hours of work done over time, broken down by project. The results can be segmented further by any number of selected fields.
Segmentations are only available on a current-value basis for the issue. For example, segmenting by "Priority" will break down the results based on the current values of the priority field rather than the values at the time the work was performed.
This report is a key tool for program managers who need an ongoing comparison of the amount of effort being applied toward different projects within a reporting period.
To drill into the results by which team members are doing the work, choose to Segment By the value of Work Logged By. Or if you've configured your JIRA projects to use a common list of Components across projects—to represent team, discipline or target device—segmenting by Component is a powerful way to slice the cross-project results.
