The capability of a system design to support operations and readiness at an affordable cost throughout the system's life is best described as ______.

• A. Maintainability
• B. Operability
• C. Reliability
• D. Supportability

Answer: (D)

The idea being tested is how easily a system can be kept operating over its entire life without letting sustainment costs spiral. This is about planning, logistics, and maintenance in a way that keeps operations ready while controlling total life-cycle cost. That broad capability is called supportability. It encompasses things like easy maintenance, availability of spare parts, effective maintenance planning, technician training, diagnostics, and obsolescence management, all aimed at affordable, reliable support across the system’s life. It’s different from reliability, which is about the probability the system will perform without failure; and from maintainability, which focuses on how quickly you can repair it when a failure occurs; and from operability, which concerns how well the system is used in operation. Here, the emphasis is the sustained ability to support and keep the system ready at a reasonable cost over time.
