👉 Spare engineering refers to the practice of designing systems, machinery, or software with redundant components or pathways that can take over in case of failure, ensuring continuous operation and reliability. This approach involves incorporating extra parts or backup systems that can be activated automatically when the primary ones fail, minimizing downtime and preventing system-wide disruptions. By anticipating potential points of failure and integrating spares, engineers enhance the robustness and resilience of complex systems, making them more dependable in critical applications such as aviation, healthcare, and telecommunications.
