An IPS element focusing on maintaining system performance throughout its life cycle is called?

• A. Operational Test and Evaluation
• B. Developmental Test and Evaluation
• C. Systems Engineering Plan
• D. Sustaining Engineering

Answer: (D)

Sustaining Engineering is the part of Integrated Product Support that keeps a system performing well over its entire life cycle. After a system is fielded, issues arise—components wear out, parts become obsolete, newer technologies offer improvements, and field feedback leads to design changes. Sustaining engineering coordinates fixes, upgrades, and modifications, manages obsolescence, and updates maintenance instructions, training, and supply chains so the system continues to meet its performance, reliability, and maintainability goals throughout its service life. In contrast, Operational Test and Evaluation assesses how a system performs in real operating conditions to determine readiness for deployment, while Developmental Test and Evaluation checks that the system meets design requirements during development. The Systems Engineering Plan is the document that outlines how the system will be developed and integrated.
