Which mandatory Key Performance Parameter (KPP) relates to the effectiveness of a military system?

• A. Force Protection
• B. Sustainment
• C. Operational Availability and Suitability
• D. Lethality

Answer: (D)

Effectiveness is about the system delivering the intended battlefield effect, and that is captured by lethality. Lethality measures the system’s ability to defeat or neutralize targets—the damage potential, accuracy, and speed at which effects are delivered to accomplish the mission. If lethality is insufficient, the system cannot reliably achieve its objectives even if other aspects perform well. The other aspects—protecting personnel and assets (force protection), maintaining operations through logistics (sustainment), and ensuring the system is ready and fit for use under expected conditions (operational availability and suitability)—are important supporting factors, but they describe how the system functions and stays usable rather than its core capability to produce the desired combat effect. So, the mandatory KPP tied to overall effectiveness is lethality.
