I can summarize test data, calculate risk-priority values, and connect failures to likely causes and controls.
POE Unit 5 • Lesson 5.14
Data Analysis and Failure Modes
Focus question: How can performance data and failure-mode analysis identify the most important weakness to correct?

Lesson Targets
What You Will Be Able to Do
Performance analysis and prioritized failure-mode report
The team prioritizes a failure using both performance evidence and risk rather than convenience or visibility.
Activity Flow
How the Lesson Moves
Each step produces a decision, artifact, or test result needed for the capstone.
1. Summarize performance
Calculate relevant statistics and compare results with requirements.
2. Analyze failure modes
Identify effects, causes, severity, occurrence, and detectability.
3. Prioritize action
Choose the revision with the strongest evidence and risk justification.
Lesson Interactive
Prioritize the Failure Modes
Apply the lesson concept to a capstone aerospace-systems scenario. Use the feedback to correct your reasoning before completing the main deliverable.
Failure-Mode Ratings
| Mode | Severity | Occurrence | Detection difficulty |
|---|---|---|---|
| A: Wheel misalignment causes route drift | 8 | 6 | 3 |
| B: Display label detaches | 3 | 6 | 4 |
Risk Priority Number = Severity × Occurrence × Detection difficulty.
Calculate each RPN, select the higher-risk failure, and match the corrective action to its cause.
Today’s Work
Main Deliverable
Performance analysis and prioritized failure-mode report
Create one focused engineering artifact that demonstrates today’s capstone progress.
- Create a data summary showing performance against each critical criterion.
- Complete a failure-mode analysis and justify the highest-priority corrective action.
