Resource Planning
Step-by-step guide
use the default for issue selection ("Default") or
any favorite filter having an ORDER BY clause containing "assignee" or
click on Gantt menu item "configure columns & rows", switch to tab "grouping rows", enable option "Group by columns below instead of auto-grouping based on ORDER-BY-clause of related JQL" and take care to have added at least column "assignee" beside all other columns you want to group by and hit finish (since Gantt-Chart version 3.2: this feature is also available for agile SCRUM boards as well as Kanban board selections).
In all cases above:
The utilization figures are rounded to one digit after the comma – if necessary – and displayed using a font size of 10px:
if that's to small to be read comfortably, move the mouse over the related figure and the number will be enlarged automatically for better readability
4. You can easily (re-)assign issues to other team members: ensure that you have configured the Gantt-Chart to display the assignee column (Gantt menu - configure columns & rows - tab "columns") and that you have enabled edit mode by clicking on the pencil icon (1). Then click on the assignee field (2) rather than by drag'n drop:
Then select your preferred project role and then the related assignee: rather than just selecting the assignee by name, you can focus on project roles like selecting all project's developers or tester etc., too. Then select a role member of the sub-list based on the chosen project role as new assignee. For sure, alternatively you can just select from all assignable users as well:
Having assigned issues to different team members, you can switch from the view above (agile board of JIRA Agile) to the default Gantt-Chart view, grouping by assignees beside other configurable aspects:
If you collapse rows of assignee, you'll get a nice overview of your team:
Per assignee row, you'll see within a single row containing all related issues, which may overlap (assignment of multiple issues to a team member in parallel). Issues are display in semi-transparency, so it becomes darker if more issues overlap each other to indicate multi-work per time unit.
Gantt-Chart versions prior to v3.0.1 have got a separate project tab panel for displaying a view for resource planning. Since v3.0.1, this has been integrated for more flexibility.
Since Gantt-Chart version 3.2, you have the ability of selecting a project role upfront to a role member.
