| Scheduling | **[Tasks without dates](https://appfire.atlassian.net/wiki/spaces/DLP/pages/315262798)**
Dates do not need to be specified when a new task is added to a box (either by creation or modification of scope definition). Tasks without dates are visible in the task tree (WBS) but aren’t shown on the Gantt chart until the start/end date is specified. Additionally, unscheduled tasks are visible in a [panel on the Resouces module](https://appfire.atlassian.net/wiki/spaces/DLP/pages/512328594).
**Note**: Existing tasks that have already been positioned on the timeline are NOT affected by the change.
The [Overdue](https://appfire.atlassian.net/wiki/spaces/DLP/pages/296851268) feature is NOT available for tasks that don’t have a start/end date. |

| **[Task dates (start/end) based on estimates - behavior](https://appfire.atlassian.net/wiki/spaces/DLP/pages/296851336)**
Change of a task duration or the estimate value results in a task being resized. The mapped value (either start or end) is updated. The other date doesn’t change (unless additional scheduling mechanisms apply)
Change of the start/end date value (behavior the same regardless of which value is mapped):
- change of the **start date** results in a task being moved.
- change of the** end date** results in a task being resized. The estimate field and task duration field reflect the change. The start date is unaffected. | n/a |
