In the past, I used to create work breakdown structures (WBS) by brainstorming with my project team using a white board, sticky notes or by projecting my notes (old organizational hierarchy feature of Microsoft Office PowerPoint, a bullet list in Microsoft Office Word or the Gantt Chart view in Microsoft Office Project).
With WBS Chart Pro, you can visually create a WBS, as it should be, and then export the results into Microsoft Office Project. The bidirectional feature is really neat (changes in WBS Chart Pro get reflected in Microsoft Office Project in real-time and vice-versa). During your weekly progress meeting, you can use WBS Chart Pro to show a graphical summary of your project.
