The Sustainment Key Performance Parameter (KPP) is mandatory for all systems and is designed to enhance system life-cycle management. The attributes for the Sustainment KPP are identified in the Capability Development Document (CDD) and Capability Production Document (CPD) and apply to all pre-Milestone C programs.
Sustainment consists of two mandatory key factors: Material Availability and Operational Availability and three mandatory supporting Key System Attributes (KSA) (Reliability, Maintainability, and Total Ownership Cost) for all Acquisition Category (ACAT) I programs. For ACAT II and below programs, the sponsor will determine the applicability of the KPP. During the Capabilities Based Assessment (CBA), the relevant sustainment criteria and alternatives will be evaluated to provide the analytical foundation for the establishment of the sustainment KPP and KSAs.
