8 = Serial and Parallel tasks =
9
10 Firstly, tasks can be added in one of two ways:
11
12 * **Serial Tasks:** Tasks are created in serial to be **performed one after the other**. A document must complete the action required by one serial task before it moves onto the next task in the plan.
13 * **Parallel Tasks:** Tasks are created in parallel to be **performed at the same time as each other**. A document must complete the actions required by all parallel tasks before it moves on to the next task in the plan.
14
15 = Insert Child =
16
17 ‘Insert Child’ inserts a** parallel task immediately below** the task that is selected in the task tree, to be performed **after** the task selected. Existing children will not be inherited. The first task added to a new plan will always be a child task.
18
19 If a child task already exists below the task for which a new child task is added, the new task will be a parallel task undertaken at the same time as the existing child task.
20
21 If no child task exists below the task for which a new child task is added, the new task will be a serial task undertaken after the existing child task is completed. This will occur only when a child is inserted to the final (bottom) existing task.

23
24 = Insert Parent =
25
26 ‘Insert Parent’ inserts a **serial task** **immediately above** the task that is selected in the task tree, to be performed **before** the task selected.
27
28 Note that a parent task cannot be added as the first task to a new plan.

31 = Insert Child Inherit Children =
32
33 ‘Insert Child-Inherit Children’ inserts a **serial task** **immediately below** the task that is selected in the task tree, to be performed **after** the task selected. All existing child tasks are inherited by the new task.

35
36 = Delete =
37
38 ‘Delete’ will delete the selected task. Note that any child tasks will not be deleted. PECOS P2P will display a warning message: click ‘OK’ to confirm deletion and ‘Cancel’ to return to the plan without deleting the task.
39
40 = Expand All =
41
42 When tasks are hidden, a plus ‘+’ symbol will appear next to the parent task that contains child tasks. To expand the parent task to display hidden children, click on the ‘+’ symbol. To **expand all hidden tasks** in the task tree click the ‘Expand All’ button.
