The Space Systems Technical Data Report (SSTDR) collects contractors' unit-level technical data and cost information across five formats to support DoD space acquisition program cost estimates and budgeting.
This report consists of five formats for collecting contractors' technical data and unit cost on Department of Defense (DoD) space acquisition contracts.
Format 1 provides unit-level space hardware technical data on product-oriented Work Breakdown Structure (WBS) elements; these WBS data are used for cost model inputs. See Sample Format 1.
Format 2 provides the detailed space hardware technical data associated with the appropriate level of indenture. There is no sample for this format.
Format 3 provides estimate at complete (actuals and estimate to complete) cost information for the units, boxes, assemblies, SEIT/PM, Support Equipment and/or software CSCIs. See Sample Format 3.
Format 4 provides specific technical data to establish the technical baseline of the proposed/contracted system. See Sample Format 4.
Format 5 provides the detailed ground hardware technical data associated with the appropriate level of indenture. There is no sample for this format.
SSTDR data shall be used by DoD component staff, including program managers, engineers, cost estimators, and financial management personnel to: (1) Review and evaluate the baseline reasonableness; (2) Provide technical inputs required to develop a program cost estimate; and (3) Collect technical and cost information to develop estimating relationships (CERs).
SSTDR primary value to the Government is its ability to support the development of program cost estimates. It is important that the data be as accurate as possible so that they may be used for their intended purpose, which is to facilitate improved budgeting.
a. This Data Item Description (DID) contains the format and content preparation instructions for the data product generated by the specific and discrete task requirements as delineated in the contract.
b. This DID shall be used in conjunction with the Contract Work Breakdown Structure (CWBS) DID, DI-MGMT-81334A, CONTRACT PERFORMANCE REPORT (CPR) DID, DI-MGMT-81466A, Cost Data Summary Report DID, DI-FNCL-81565A, Cost & Software Data report DID, DI-FNCL-81, Detailed Mass props Status report DID, DI-GDRQ-81231
The same WBS shall be utilized for the Integrated Master Plan (IMP), Integrated Master Schedule (IMS), CPR, and Contractor Cost Data Report (CCDR) as applicable.
c. The SSTDR shall be used to obtain cost and technical information on contracts for programs that are ACAT 1 or 2 and any other program as designated by the PEO or Comptroller.
d. The SSTDR shall be required no more frequently than yearly. Data contained in the formats shall be as of the accounting month end of the milestones specified, with delivery no more than 90 days after milestone completion. This requirement may be tailored through contract negotiations. All formats are not required (or even normally provided) at the same time. Each format contains unique data that apply mainly to specific program phases and maturity. Format 2 and 5 are recommended at CDR and IOC milestones only and should always be accompanied by Format 1. Format 4 is usually provided only in phase A (to PDR) of the program.
e. Unless otherwise provided in the contract, data reported in the SSTDR shall pertain to all authorized contract work, including both priced and unpriced effort.
f. Submission of Formats 1 & 3 using a product-oriented WBS in accordance with the WBS Handbook, MIL-STD-881, and the CWBS DID, DI-MGMT-81334A, is mandatory. (Note: For contracts that require CCDRs, the CWBS shall be developed, approved, and maintained in accordance with DoD 5000.4-M-1, Cost and Software Data Reporting Manual, and the CWBS DID.)
Certain aspects of the report are subject to negotiation between the Government and the contractor, such as the level of detail to be reported in Format 1 (normally this will be at unit, assembly, or CSCI as defined in MIL-STD-881 for space systems). Although the SSTDR Contract Data Requirements List (CDRL) is subject to tailoring, requiring more information (e.g., additional technical parameters) in the SSTDR CDRL than specified in this DID is contrary to DoD policy. All negotiated reporting provisions shall be specified in the contract.
