Use this window to define, delete and update resource groups. Examples of resource groups are engineers, developers, etc. You also may think of a resource group as a single person. Each resource group has a cost and a capacity. When entering a new resource group, you should make sure that cost and capacity information is added; otherwise the calculation will lack essential information and the project will seem more profitable than it should. For the description of each tab in the window, follow the appropriate link: Cost, Capacity and Activities.
A Project Reporting resource will have the Employee and Standard Price tabs available, and the Cost tab will be disabled. If the resource group is a Project Reporting resource, refer Internal Price for more information.
