The functions of a system may usually be split into subfunctions. Failure modes at one level in the hierarchy may be caused by failure modes on the next lower level. It is important to link failure modes on lower levels to the main top level responses, in order to provide traceability to the essential system responses as the functional structure is refined. This is shown in Figure 3.6 for a hardware structure breakdown. Figure 3.6 is further discussed in Section 3.6.5.
