Work breakdown structure (WBS)
A work breakdown structure (WBS) is a tool to help you breakdown the approach to complete large projects. By breaking the project into smaller pieces the Gantt widget will become much more clear and understandable.
Enabling WBS column in the features tab is a straightforward process. With this enabled a column appears in the Gantt widget client. This can be used to organize and structure the tasks.
