In particular, On the other hand, However, Similarly, As a resultant implication, In this regard, Based on integral subsystem considerations, For example, Thus, With respect to specific goals, Interestingly enough, Without going into the technical details, Of course, To approach true user-friendliness, In theory, It is assumed that Conversely, We can see, in retrospect, It is further assumed that Further, In summary, It should be noted that To further describe and annotate, Specifically, a large proportion of interface coordination communication a constant flow of effective communication the characterization of specific criteria initiation of critical subsystem development the fully integrated test program the product configuration baseline any associated supporting element the incorporation of additional mission constraints the independent functional principle the interrelation of system and/or subsystem technologies the product assurance architecture must utilize and be functionally interwoven with maximizes the probability of project success, yet minimizes cost and time required for adds explicit performance limits to necessitates that urgent consideration be applied to requires considerable systems analysis and trade-off studies to arrive at is further compounded when taking into account presents extremely interesting challenges to recognizes other systems' importance and the necessity for effects a significant implementation of adds overriding performance constraints to mandates staff-meeting-level attention to is functionally equivalent and parallel to the sophisticated hardware. the anticipated fourth-generation equipment. the subsystem compatibility testing. the structural design, based on system engineering concepts. the preliminary qualification limit. the evolution of specifications over a given time period. the philosophy of commonality and standardization. the greater fight-worthiness concept. any discrete configuration mode. the management-by-contention principle. the total system rationale. possible bidirectional logical relationship approaches. the postulated use of dialog management technology. the overall negative profitability.
