I can analyze repeated mission trials and select a revision supported by data.
POE Unit 3 • Lesson 3.17
Mission Testing, Data Collection, and Iteration
Focus question: How can mission data distinguish a random failure from a repeatable design or control-system problem?

Lesson Targets
What You Will Be Able to Do
Mission test analysis
The analysis identifies trends, anomalies, success rate, and the highest-priority revision.
Activity Flow
How the Lesson Moves
Each step builds the control-systems reasoning needed for today’s deliverable.
1. Run controlled trials
Hold conditions constant and record mission events.
2. Analyze performance
Calculate success rate, timing, error, and repeatability.
3. Revise one cause
Choose a change linked to the strongest evidence and retest.
Lesson Interactive
Mission test analysis Practice
Apply the lesson concept to an aerospace rover or VEX ground-support scenario. Use the feedback to correct reasoning before documenting the main deliverable.
Mission Trial Data
| Trial | Time (s) | Stop Error (mm) | Result |
|---|---|---|---|
| 1 | 82 | 8 | Pass |
| 2 | 85 | 11 | Pass |
| 3 | 84 | 9 | Pass |
| 4 | 118 | 52 | Fail |
| 5 | 83 | 10 | Pass |
Analyze the Trials
Preserve anomalies, investigate them, and distinguish one unusual event from a repeatable pattern.
Today’s Work
Main Deliverable
Mission Test Analysis
Create one focused engineering artifact that demonstrates today’s learning.
- Summarize at least five trials using success rate and one quantitative performance measure.
- Identify one repeatable failure pattern and propose a revision tied directly to the data.
