The Visio 2010 add-in for WBS Modeler is intended to improve the project planning process by giving the opportunity to generate project plans from a work break-down structure (WBS) using a graphical representation of elements. The WBS Modeler can either be used to visualize and edit an existing project plan or to create a new project plan in Visio Professional 2010 or Visio Premium 2010 and then export it to Microsoft Project 2010/2007 to carry out the next planning steps. The Application enables effective integration of Visio with Microsoft Project and provides an approach to visually and graphically create, edit and modify project plans using Visio.
