How is life cycle cost savings achieved in the provided example?

• A. Reducing maintenance hours to save cost.
• B. A reduction of 10% in overall life cycle cost achieved by trading 5% of point to point surface communications range KPP for greater component reliability.
• C. Increasing production speed.
• D. Outsourcing to reduce cost.

Answer: (B)

The main idea is that long-term savings come from balancing performance with reliability to lower total costs over the system’s life. In the example, a small concession on a performance parameter—the 5% reduction in the point-to-point surface communications range Key Performance Parameter—allows using components with greater reliability. That increased reliability reduces failures, maintenance needs, and downtime across the system’s life, which adds up to a 10% reduction in overall life cycle cost. The gain comes from how reliability drives down operating and maintenance expenses, often outweighing a modest drop in performance. Other options don’t describe this mechanism. Simply cutting maintenance hours or increasing production speed doesn’t capture a measured trade-off that leads to a quantified life cycle cost reduction, and outsourcing, while potentially cost-saving in some cases, isn’t the reliability-driven trade-off shown here.
