* Any given system can be organized into a hierarchy composed of segments and/or<br />
elements of succeedingly lower and less complex levels, which may in themselves be<br />
termed “systems” by their designers. In order to avoid misunderstandings, hierarchical<br />
levels for a given mission must be defined early.<br />
