Feedback Loop

Testing becomes powerful when feedback changes the next version — and the changed version is tested again.

Student Materials
Criterion D + Systems
T
TESTUse a simple relevant method that generates data.
F
FEEDBACKCollect evidence from users/performance.
↻
IMPROVE + RETESTChange one feature and check whether the output improves.

System Connection

L59 · 02
Closed-loop systems connect directly to iteration.Systems + evaluation
Mini-Lesson
One focused test is better than three vague opinions
L59 · 03

Vague

“Do you like it?”

Useful

“Complete the intended task three times. I will record successful attempts and ask for one 1–5 ease-of-use rating.”

D.i applicationGenerate data
Feedback Carousel
Three short testers
L59 · 04
Test

Run the same core test with several peers.

TESTER 1

Perform

Use the prototype in the intended task.

TESTER 2

Observe

Record data; do not coach unless safety requires it.

TESTER 3

Feedback

Collect one specific comment/rating.

Rotate efficiently.Authentic enough for rapid cycle
Required Improvement
Evidence must change something
L59 · 05

Choose one weakness supported by the data.

EvidenceWhat failed / slowed / confused?
→
ChangeModify one feature or system step.
→
RetestRepeat the same measure where possible.
D.iii applicationOne required improvement
Compare Before / After
Did the change help?
L59 · 06
“Before the change, _______. After the change, _______. Therefore the evidence suggests _______.”
Evaluation languageData → conclusion
Exit Reflection
Feedback changed the system
L59 · 07

Finish one sentence.

“The most useful feedback was _______ because it caused me to _______.”
