In the YouTube clip,  “bad actors” were identified by:

With n=2 staged spares, compute the probability of no stockout during the mission.   Solution is a percentage, round to 2 decimals (ie, 45.67)

What is a primary advantage of maintaining an LSA-R throughout development and operations?

Which statement best distinguishes Performance-Based Logistics (PBL) from a traditional transactional support model?

Hypothetical situation: During Test & Evaluation, a deficiency is discovered. How should that flow work to minimize error?

Risk Sensitivity Index – A team runs a Monte Carlo simulation on failure risk for a missile guidance subsystem. The model outputs an estimated risk of failure of 0.0023 with a 95% confidence interval of ±0.0008. What are the lower and upper bounds of the 95% confidence interval? Is this system within a safety requirement that sets the max allowable failure rate at 0.003? [lower]  format – 4 decimals ie, 0.1234 [upper] format – 4 decimals ie, 0.1234 [yes_no]

Example of governance objectives include:

Requirement Verification Rate – A systems engineering team is validating the architecture of a satellite-based subsystem. Out of 120 requirements, 94 are fully verified through simulation or test. What is the verification rate (as a percentage)? If the acceptable threshold is 85%, does the system pass this governance metric? [percentage]  format: xx.xx [yes_no]

In regards to the case study: The Reliable and Maintainable F-119 Engine   Pratt & Whitney’s F-119 maintainability goal included “one-deep” LRUs. What does “one-deep” mean?

HFE spans procedures, workload, training, alarms, maintainability—not just ergonomics.
