Which statement accurately describes maintenance concept?

• A. It describes the deployment schedule for fielded systems.
• B. It is a plan for the procurement of new systems.
• C. It is a brief description of maintenance considerations, constraints, and plans for operational support of the system/equipment under development.
• D. It defines the metrics for supplier performance.

Answer: (C)

Maintenance concept outlines how the system will be kept operational during development and throughout its life cycle, including the maintenance tasks, constraints, and the plan for ongoing operational support. That description matches a concise brief of maintenance considerations and plans for how the system will be supported once in use. The other ideas focus on when deployment occurs, how new systems are purchased, or how supplier performance is measured, which are not about planning and describing sustainment and support for the system under development.
