Working with Consultant Data Overview
The Consultant charts provide an overview of the consultant budget for your plan, and the Consultants grids allow you to assign consultants to each level of the plan. Typically, you assign consultants at the lowest level of the plan's work breakdown structure (WBS); however, it is possible to budget them at any level.
If you budget consultant costs at a lower level in the WBS, then the higher level line items summarize the expenses of their descendants. For example, budgeted consultant costs at the task level roll up to the phase level.
