A hierarchic labeling scheme should be used such that major labels are used to identify major systems or workstations, subordinate labels are used to identify subsystems or functional groups, and component labels are used to identify each discrete panel or console element.
Additional Information: Labels should not repeat information contained in higher level labels.
Figure 11.12 provides an example. Hierarchic labeling will help to reduce confusion, search time, and redundancy. 0700
