The 881 C DiD Outlined
For organizations venturing into the world of government defense contracts, the Department of Defense provides guidelines for the development of a standardized Work Breakdown Structure (WBS). The principal document that describes these structures is formally titled “Department of Defense Standard Practice Work Breakdown Structures for Defense Materiel Items”, commonly referred to as the 881 DiD. You can download this document here from the DoD website or Google MIL-STD 881C to find various sources for download.
Such standards are critical in providing the government and contractor with a uniform and consistent approach to a program’s data structure. This assists with good communication between the two parties throughout the lifecycle of the program. The benefits of this standardized approach include clear segregation of the materiel item into its component parts, effective assignment of management and technical responsibilities, aid with the status tracking for all elements of the program’s cost, schedule and technical performance and consistent structure for the earned value management system.
Above all else, these standards provide a clear starting point for program development down to and including level four of the WBS. At the same time, they provide both unambiguous guidelines and flexibility for program managers below the forth level, so there are no restrictions when working to match the government reporting requirements with a realistic schedule that can be executed by the contractor.
The 881C DiD provides 11 standard work breakdown structures with appendices a – k. Each WBS is clearly defined with a punctuated significant WBS code and description. Each WBS is designated specifically for a particular type of defense system and is listed in the following section.
