In particular, this solution is used by project managers to launch a new Windows SharePoint Services team site and to collect data that will be used to manage a project. It shows how various Microsoft technologies can work together to improve and simplify business processes, with an emphasis on Microsoft Visual Studio 2005 Tools for Office.
