6.5      Network Operability and Tolerance Analyses

As mentioned earlier, critical considerations in assessing a mission’s operational effectiveness are identifying, representing, and measuring dependencies between entities (e.g., programs, functions, technologies) necessary for its successful execution. The importance of understanding entity relationships is many-fold. Primary, is to study the ripple effects that degraded performance in one entity has on the performance of other dependent entities across a relationship network that characterizes a mission or capability. The ability of a mission or network to absorb the effects of nodal degradation while maintaining an acceptable level of operational effectiveness is known in FDNA as network ...
