MIL-STD-881C - dated October 3, 2011
MIL-STD-881, latest revision C, is the “Department of Defense Standard Practice” for the development of “Work Breakdown Structures for Defense Materiel Items”. This Standard is to be used by all Department of Defense (DoD) Departments and Agencies and should be included as a contract requirement; it is mandatory for all programs subject to DoD Instruction 5000.02.
“A Work Breakdown Structure (WBS) provides a consistent and visible framework for defense materiel items and contracts within a program.” With uniformity of definition and a consistent approach used for development of a WBS, the result is improved communication in the acquisition process and also direction to industry in extending contract work breakdown structures.
The MIL-STD-881C establishes summary Work Breakdown Structures for aircraft systems, ship systems, space systems, surface vehicle systems, etc. All of these summary Work Breakdown Structures depict the first three levels of the WBS that are common to most generic systems. The summary WBS is developed by the procuring agency, approved by the Cost Analysis Improvement Group (CAIG), and normally provided to the contractor in a Request for Proposal. The contractor is expected, to expand the WBS down to a level where work will be authorized, planned and managed.
