This appendix provides the WBS elements common to all types of
systems. Applicable Government and non-Government documents are
listed. Definitions for the common WBS elements are provided in this
appendix. Unique uses of common elements are also included to better
define the related systems.
Elements defined in this Appendix are elements common to all acquisition
programs developed by the Department of Defense. The efforts associated
with common elements should be placed at the level where they support a
specific element. Common elements can be found at all levels of a
G: Surface Vehicle System as an example, common elements found at Level 2
of the WBS capture efforts associated with the system as a “whole” (I.e.
training for the entire surface vehicle system). Level 3 common elements will
support Level 2 elements such as the primary vehicle or secondary
vehicle. Level 4 common elements are not often shown however, they
support the subsystems captured at Level 3 (i.e. training for the navigation
