... To complete the proposal with the required detail, PIs must engage accounting and engineering professionals from their own organization or a teaming organization to construct a work breakdown structure (WBS) , which is a set of budgetary spreadsheets showing all planned expenditures according to a proposed schedule for mission development, from selection through design definition (Phase B)

... of approximately 150 pages is generated for a second comprehensive TMCO review, which is often conducted by a subset of the same panelists who carried out the Step 1 review. The panel, along with program and NASA Headquarters representatives, visits one of the primary teaming institutions as part of Step 2.
