A work breakdown structure (WBS) is a description of the work to be done for a project.
It is a hierarchy of tasks that represents the composition of work, cost, and duration of each task.
To create a WBS, you can use three types of nodes.
Root node: Root node is the project header node.
This is created automatically and is shown by default after you click Advanced WBS.
When you transfer a project quotation to a new project, the root node becomes the main project.
When you add the project quotation to an existing project, the root node is ignored.
Project node: In the WBS, you can have multiple sub-projects which are called project nodes.
Activity node: Activity nodes contain the project tasks.
Standard - You can add tasks to lines of type Project and Standard.
Summary - You can add summary lines to lines of type Project.
Detail - You can add detail lines to lines of type Summary and Detail.
You can use these activity types.
You can add several activities under the root node or a project node.
You can add an activity under an activity. You cannot add a project node under an activity.
