and, in some cases, advanced attributes (AAs) that address particular aspects
of systems engineering. A theme is a subdivision of a focus area that defines
a related set of specific practices to put those practices in context. A specific
practice is an activity that is essential to accomplishing the purpose of a focus
area or that helps accomplish the purpose of the focus area effectively and
efficiently. Specific practices are associated with specific levels of capability
within each focus area.
