I.3.1 Application of Common WBS Elements (Appendix L). Common WBS elements (i.e., Integration, Assembly, Test and Checkout; Systems Engineering; Program Management; System Test and Evaluation; Training; and Data) should be applied to the appropriate levels within the WBS for which they support. For example, if Systems Engineering is required to support a Level 3 WBS element, the Systems Engineering WBS element would appear at Level 4 of the WBS under the Level 3 element it supports.

I.3.2 Key Principles in Constructing a WBS. In the appendices of MIL-STD-881C, the WBS is defined to Level 3 of that structure and in some cases Level 4 or 5. In order to ensure consistency across all systems and developers, WBS elements in the appendices are extended to levels 4 and 5.

1) The reporting level of the WBS is typically at Level 3 except for those items considered high cost, high risk, or high technical interest. For those elements, extension of the WBS to lower levels is necessary to get needed visibility, but only for those elements. Not all WBS elements should be extended to the lowest level. In addition, for each system being defined only those WBS elements that define the system shall be used. The purpose of going below level 3 within the appendix is to ensure that the higher level elements include the proper lower level elements and when required to report at a lower level, those elements at level 4 or 5 are consistent across all systems and developers.

2) In each of the appendices, an element entitled “Other” is available to provide flexibility within the WBS for new or additional WBS elements that are not identified or defined in the Standard. These “other” elements would be used if, for example, a new subsystem or modified subsystem is defined and it does not currently appear in the appendices of MIL-STD-881C.

3) A key to WBS development is the principle that if you can associate the WBS element with the element it supports, it should be included within that element. This is called the 100% rule, which states the next level of decomposition of a WBS element (child level) must represent 100% of the work applicable to the next higher level (parent level). For example, the parent level WBS (radar system) has three child elements – transmitter, antenna, and receiver. If the program manager decides he/she wants more visibility into the transmitter subsystem and pulls it out of the radar system and makes it a level equal to the radar, it distorts the effort and resources that are required to complete that radar system because it assumes the transmitter is not included (i.e., a child element to the radar is now missing within the WBS structure).

4) In some cases, items cannot be specifically associated with the element they support. For example, software is a critical element of that transmitter subsystem. Under normal circumstances, software would be the child level to the parent level transmitter. However, depending on how software is developed, the software may include more functionality than just for the transmitter subsystem. It may include functionality for the receiver as well. In this case the software cannot be associated with the specific elements they support, due to an inability to determine the effort for each functionality developed. Therefore, it is appropriate to associate that software to the next highest level (radar system) of the WBS. It is still included as a part of the radar system at the child level, but we are not trying to allocate effort across multiple WBS elements where we are unable to determine what level of support each gets.

5) Intelligence (Intel) efforts (security, threat, mission data) are often considered late in the acquisition cycle, even after contract award. Identifying where Intel is needed reduces risk and affords a much better opportunity to manage cost, schedule, and performance. The WBS Standard portrays systems in a product-oriented WBS, identifying and considering potential intelligence information and costs using the existing Component cost estimating processes.

I.3.3 Numbering of the WBS. In each appendix, the work breakdown structure for that commodity has been numbered for reporting purposes only. The purpose for the numbering is to provide a consistent approach to identifying and managing the WBS across like systems regardless of vendor or service. The numbering system is numeric; however, several unique issues arise across appendices which require the numbering system to be modified to accommodate the anomalies.

I.3.3.1. “Other” WBS Elements. All appendices contain a WBS element titled as “Other” at the subsystem, element (product) levels that are restricted for products that have not been envisioned or predicted within the defined WBS elements in the Appendix. If it is determined that the “other” WBS is not needed, this element and assigned WBS number should be deleted and not used in the WBS. If it is determined that the “other” element is needed, then each element must be defined and the word “other” replaced by the newly defined WBS element using the assigned WBS number from the appropriate appendix. The newly defined element must be approved by the Government Program Manager and the representative contracting officer.

I.3.3.2 (1…n) WBS Element Definitions. Several appendices identify WBS elements with (1…n) or similar to denote that one or more of that type of item may be used. Where this structure occurs, the parent WBS (e.g., 1…n) shall be decomposed to the next level and then each child WBS use the appropriate WBS title for each element as well as the WBS numbering identification. For example, if a missile system has multiple propulsion subsystems, each Propulsion Subsystem (1…n) shall have a WBS name designation (for example, “Solid Rocket Motor”), and the element Propulsion Subsystem 1 would be at the child level of the parent WBS element (Propulsion Subsystem 1…n) as would Propulsion Subsystem 2 (for example, “Liquid Rocket Engine”), and so forth. Each WBS should be detailed down to the element’s lower level (as defined in the appendices) whenever possible, and assigned the next available WBS number in sequence according to the parent child relationship as shown below.

1.1.2. Propulsion Subsystem (1…n)
1.1.2.1. Solid Rocket Motor
1.1.2.2. Liquid Rocket Engine
1.1.2.3. Backup Rocket Motor

I.3.4 Unmanned Maritime SystemWBS guidance. The following guidance may be used to help determine which Unmanned Maritime System WBS element should include different types of material:

a. If an item has more than one function it is grouped with its primary function.
b. Welding materials, hardware, fittings, and similar items are included with the functional system.

k. Electric power cabling is included with the system that consumes the power. The boundary is at the power distribution system bus bar.
l. If the electrical cabling cannot be easily separated into subsystems because there is a single wire harness, there may be a single WBS element for cabling.
m. Built-in tanks that have at least one surface homogeneous with principal structure are included in the structural group. All other tanks are included in the system they support.
n. Items such as hull fasteners, pipe hangers, associated valves, valve operators, strainers, filters, flex connections, resilient and sound mounts, are included within the system they support.
