What is evaluated if a system does not meet the Key Performance Parameters?

When a system does not meet the Key Performance Parameters (KPPs), the evaluation centers on the selection of the concept or system because KPPs represent crucial thresholds that a system must achieve to be deemed effective and acceptable for use. KPPs are established at the beginning of the acquisition process to ensure that the system can fulfill its intended mission. If these parameters are not met, it often indicates a fundamental flaw or misalignment in the concept or design chosen at the start of the project.

This prompts a reassessment of the initial technological choices, design specifications, and overall approach to determine if a different concept or system would be more suitable to meet the operational requirements dictated by the KPPs. Addressing the root causes of the shortfall often involves revisiting the initial decisions made regarding the system's capabilities, architecture, and potential trade-offs for future development. Therefore, a thorough evaluation of the concept itself is essential to identify whether alternate solutions may be more effective in achieving the desired performance outcomes.
