What is the Work Breakdown Structure?
Break a project into deliverables and smaller work packages in levels.
Enter the main deliverables, then list the tasks beneath each one with a numbered code. The structure shows how the whole project is made up of smaller pieces.
Projects go wrong when nobody can see who does what and by when. A clear chart, register or report keeps a team looking at the same picture.
