Repair parts should be prioritized for inventory levels based on which factors?

• A. Based on mission criticality, failure rates, lead times, and criticality of asset to mission
• B. Based on color and size of parts
• C. Based on vendor proximity only
• D. Based on historical spend alone

Answer: (A)

Prioritizing repair parts with a risk-based mindset means weighing how crucial the asset is to operations, how likely the part is to fail, how long it takes to get a replacement, and how essential keeping that asset running is to the mission. When a part supports a mission-critical asset, has a high failure rate, and has a long lead time, the risk and cost of a stock-out are high, so that part should have higher inventory priority, with ample stock and timely replenishment. Conversely, items tied to less critical assets, with low failure frequency, or that can be sourced quickly, can be kept in lower quantities and managed with leaner ordering.

That combination—asset criticality, failure rates, and lead times—captures both the risk of downtime and the practicality of replenishment, ensuring resources are focused where disruptions would hurt the mission most. The other factors listed don’t align with this risk-based approach: color and size don’t affect demand or downtime, proximity alone ignores reliability and criticality, and historical spend ignores failure risk and renewal timing.
