Select the Department of Defense's decision-support system that manages the process by which DoD develops and acquires weapons and other systems.

• A. Planning and Programming System
• B. Joint Requirements System
• C. Defense Acquisition System
• D. Mission Planning System

Answer: (C)

The key idea here is the end-to-end process the DoD uses to develop, procure, and sustain weapons and other systems. The Defense Acquisition System provides the decision-support framework that guides programs from initial concept through development, testing, production, deployment, and ongoing support. It structures required milestones, reviews, documentation, and oversight so that cost, schedule, and performance are balanced and managed throughout the lifecycle. This makes it the direct mechanism by which the DoD governs how new weapons and systems are conceived, approved, funded, and delivered to the field.

The Planning and Programming System relates to planning and budgeting decisions rather than the entire acquisition lifecycle. The Joint Requirements System focuses on defining what capabilities are needed, not on how those capabilities are developed and acquired. The Mission Planning System is about planning specific missions, not the overall acquisition process.
