What percentage of the point to point surface communications range KPP was traded for greater component reliability in the affordability analysis?

• A. 5% of KPP
• B. 10% of KPP
• C. 15% of KPP
• D. 20% of KPP

Answer: (A)

In affordability analyses, you often make a trade-off between performance and reliability: you can sacrifice a portion of a KPP to gain greater reliability through better components, redundancy, or tighter manufacturing controls. For this scenario, a small reduction in the point-to-point surface communications range, specifically 5% of that KPP, is chosen to achieve higher component reliability while keeping the overall capability within an acceptable level. The 5% figure represents a modest, conservative sacrifice that yields meaningful reliability gains without eroding the essential function of the system. Larger reductions in the range (such as 10%, 15%, or 20%) would indicate a much bigger hit to performance, which typically isn’t justified if the goal is to balance cost, risk, and schedule while improving reliability.
