What are "Key Performance Parameters" (KPPs) in systems acquisition?

Key Performance Parameters (KPPs) are defined as critical attributes that are essential for the effectiveness and success of a system within systems acquisition. These parameters establish the threshold and objective values necessary for satisfying the operational requirements of a system. KPPs serve as key metrics that acquisition programs must meet to ensure that the system will fulfill its intended purpose, contributing directly to mission success. In essence, KPPs delineate the minimum acceptable performance levels needed to achieve desired operational effectiveness, ensuring that resources are allocated effectively and that the resulting system meets the operational needs of the users.

The concept of KPPs is vital in guiding both the design and development of the system, ensuring that the focus remains on the most critical aspects rather than on less important features or options. This prioritization allows acquisition teams to make informed decisions and trade-offs throughout the development process, aligning with strategic goals and requirements set forth by stakeholders.
