You can use Time Tracking, Story Points or both as tasks duration. To define this, please use the Gantt configuration.
If no estimate is set, the default duration from the configuration is used.
To adjust duration, mouse over the right end of the task bar and once the mouse pointer changes to the resize tool, click and drag left or right to set the desired duration. If you are using Jira Time Tracking, the Original Estimate field value will be updated for issues with no time logged and Remaining for the issue with time logged. If you are using Story Points - the number of story points will be adjusted based on the ratio defined in the configuration.
You can also adjust duration by changing the value of the Jira fields themselves.
In Structure.Gantt, duration for each task can be calculated in one of four ways:
By default, task durations are calculated automatically, based on each task's work estimate, the calendar, resource availability and the Work Estimates settings.
To adjust the duration of these tasks:
- Edit the task's work estimate fields, or
- Drag the left or right side of the task bar.
Dragging the right side of a task bar will cause the task's work to be updated and its duration to be recalculated.
To adjust the duration of a fixed duration task, drag either side of the task bar. This will update the task's Start or Finish Date, and the duration will be adjusted accordingly.
|Adjusting the duration of a fixed duration task does not affect its work estimate.|
When tasks are scheduled based on sprints, they have a fixed duration corresponding to the length of the sprint. It is not possible to adjust the duration of these tasks, except by removing them from sprint-based scheduling or changing your sprint duration settings.
Tasks can also be assigned a fixed duration based on a Jira field or formula, by assigning a Fixed Duration Attribute in the Gantt Configuration.
