Which practice most improves life cycle cost by considering sustainment early in design?

• A. Early consideration of supportability and maintainability in system design
• B. Expanding the supplier base
• C. Reducing test requirements
• D. Accelerating production

Answer: (A)

Focusing on sustainment early in design reduces life cycle cost by making the system easier and cheaper to operate and maintain over its entire life. When maintenance, supportability, and logistics needs are considered from the start, you can design for easier field repair, simpler spare parts management, and faster maintenance planning. That leads to less downtime, lower spares holdings, fewer specialized tools, and longer intervals between failures, all of which shrink the total cost of ownership from procurement through disposal. Techniques such as modular design, standardized interfaces, and built-in health monitoring help achieve these gains by reducing maintenance effort and supply chain complexity. Expanding the supplier base can help with competition or resilience, but it doesn’t automatically reduce sustainment burden or total life cycle cost. Reducing test requirements may cut upfront costs but can increase risk and downstream costs if failures aren’t detected. Accelerating production speeds time to field but doesn’t address how the system will be supported, and can even raise sustainment costs if rushed design leads to reliability or maintainability issues.
