Critical technologies should be demonstrated before which stage in a defense program?

• A. Concept refinement
• B. Production
• C. Deployment
• D. Fielding

Answer: (B)

The main idea is to prove that any technology critical to the system is mature and will perform as required in a realistic environment before committing to large-scale production. Demonstrating these technologies early helps verify they can be integrated with the rest of the system, meet performance requirements, and be manufactured at the needed scale. This reduces the risk of costly late design changes, schedule slips, or budget overruns once production starts.

By showing a critical technology works under realistic conditions (often at TRL 6–7, in a relevant environment), the program gains confidence that the tech won’t become a bottleneck during production. If you wait until production, you’re already locked into procurement, so any underperforming technology could trigger costly redesigns and resets in the schedule.

Concept refinement happens earlier, when the tech hasn’t yet demonstrated viability. Deployment and fielding come after production, so they’re downstream of the decision to produce.
