Which mandatory KPP ensures a system can be maintained and supported throughout its lifecycle?

Which mandatory KPP ensures a system can be maintained and supported throughout its lifecycle?

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

Answer: (A)

Sustainment focuses on keeping a system alive and usable across its entire life cycle. When it’s a mandatory performance parameter, the design and development process must explicitly address maintenance ease, logistics support, spare parts, training, and upgrade paths. This ensures the system can be repaired, updated, and kept in operation without prohibitive cost or downtime, from field deployment through retirement. In practice, sustainment drives choices like maintainability features, support equipment, contractor and depot concepts, obsolescence management, and total ownership cost, all of which support reliable operation over time. Operational Availability and Suitability centers on whether the system is ready and appropriate for its mission when needed, which is about readiness and fit in use rather than guaranteeing ongoing maintenance and support capabilities. Lethality concerns the system’s effectiveness in defeating targets, a combat performance metric. Force Protection relates to safeguarding personnel and assets. None of these directly ensures lifecycle maintenance and support in the way sustainment does.
