Here is a work breakdown structure diagram.
The work breakdown structure can be pictured like an organizational chart, with the highest level being the project itself, and the various levels under that consisting of increasingly more detailed breakdowns of the scope of the project. Although it can take the form of an organizational chart, it does not show who does the work, but simply displays the hierarchy of the various levels of decomposition of the scope.
This is a generic WBS template for kick-start the diagram
