In the Object Manager, a task is work to be performed toward completing a project.
This image provides a visual overview of the Object Manager Model.

Tasks can be broken down into a hierarchy, which is known as a Work Breakdown Structure (WBS), to help keep track of all the tasks. Each task is given a name and a place in the task hierarchy.
Tasks are work that someone or something (for example, a machine) needs to do. A task can be a work order, a road design task, and so on. One task can be a component of another, creating a dependency. Each task is of a certain type. For each task type, there is a tool used to perform that type of task. The task type Alignment, for example, is performed using the Alignment Design tool.
Tasks provide the features needed to do the task, and a way to add results data to the model.
Summary tasks are used to divide and break down the activities into achievable tasks. For instructions on adding a summary task, see Insert a Summary Task.
Viewing Tasks
In the task section, you can see all the tasks added to the shared model in a list. If you select one of them you can see details on the task in the right panel, such as when it was created, last updated, and if the task has subtasks. Under activity in the right property panel, you can see all the activities related to the selected task, who it was done by, and when it was done.
You can also view tasks in the Explorer Pane. The example below shows a task hierarchy structure with summary tasks being used as containers leading down to an Import task called Import L_20000.XML. This task creates creates objects of the CantSpecification and LinearElement type.
