The connector synchronizes Project, Resource and Task data between the two systems. Project Managers, Resource Managers continue to work in the EPM environment while the development team works in the development environment, i.e. VSTS, and data seamlessly flows between the two systems. Updates to work items in VSTS are automatically applied to the corresponding assignments and tasks in Project Server and vice versa. Project Managers have complete control over the inflow of the actuals into the project plan.  In addition, resource management functions for all development projects, like managing time and utilization for resources working across multiple projects, team staffing etc. can be performed in Project Server. Lastly, portfolio and program level reports can easily be generated for projects being executed in VSTS and managed in Project Server.
