Which statement about the relationship between supportability and system design is true?

• A. The design phase has no impact on supportability
• B. Designing for reliability and maintainability during design phase reduces lifecycle support requirements
• C. Logistics footprint is independent of design
• D. Spares are only considered after deployment

Answer: (B)

Design decisions made early that target reliability and maintainability directly reduce the ongoing need for support activities, spare parts, and overall logistics effort over the system’s life. When the design anticipates failures, enables quick repairs, and uses modular, standard components, downtime drops and maintenance complexity drops, which lowers lifecycle support requirements and the logistics footprint. This is why designing for reliability and maintainability during the design phase yields fewer future support needs. The other statements miss this link between design and supportability: ignoring design impact would overlook how easy or hard it is to maintain; the logistics footprint changes with design choices like part standardization and serviceability, not independently of them; and spares are planned upfront, not only after deployment, to ensure readiness and minimize downtime.
