In a Failure Reporting, Analysis, and Corrective Action System (FRACAS), which metric measures the average time from failure occurrence to the closure of a corrective action?
Answer: Corrective Action Cycle Time
Corrective Action Cycle Time tracks the elapsed time between initial failure report and formal corrective action closure, indicating FRACAS process effectiveness.
A Reliability Growth Management Plan (RGMP) document should include which of the following?
Answer: Planned growth curve, management strategy, and milestone gates
An RGMP defines the reliability growth curve targets, the test-fix-test strategy, and decision gates at which growth progress is assessed.
Which IEEE standard is most widely referenced for software reliability documentation and measurement?
Answer: IEEE 1633 (Recommended Practice on Software Reliability)
IEEE 1633 provides recommended practice for software reliability measurement, modeling, and reporting throughout the software lifecycle.
When a reliability engineer documents a Weibull analysis result with β < 1, what does this indicate about the failure population?
Answer: Failures are decreasing over time, indicating infant mortality
A Weibull shape parameter β < 1 corresponds to a decreasing hazard rate, characteristic of early-life (infant mortality) failures.
A program's Reliability Qualification Test Report shows the demonstrated MTBF falls below the required MTBF. What is the correct next documented action?
Answer: Document a waiver or deviation request and initiate a corrective action plan
When demonstrated reliability falls short, the engineering process requires a formal waiver/deviation document and a documented corrective action plan before proceeding.
Which element of a Reliability Block Diagram (RBD) report is essential for auditors to verify that the model matches the actual system architecture?
Answer: Traceability matrix linking each block to its system component or assembly
A traceability matrix proves each RBD block corresponds to a real hardware or software element, ensuring the model accurately represents the system.
In MIL-STD-2155-compliant failure analysis reports, the 'verification of fix' section documents what?
Answer: Statistical proof that the corrective action eliminated the root cause
Verification of fix requires documented evidence—test data or analysis—confirming that the implemented corrective action actually eliminated the identified root cause.
