Lesson 4 · Refining
Day 4 · 30 min · the dress rehearsal
🎓 PHASE 1 · DAY 4
Your biggest blind spot is everything you consider "obvious". A colleague finds those gaps in 30 seconds — better today than tomorrow in front of the stakeholders.
2
silent testers
24 hrs
buffer for fixes

help during the test
☑️ Your dress rehearsal
Give the QR code to 1–2 colleagues who do NOT do the task
Real strangers — not people who would figure it out anyway.
Stand by silently and take notes
Where do they hesitate? Where do they scroll back? Every hesitation = a missing detail.
Fix it today
Targeted small fixes — don't overthink.
⚠️
The 3 killers
- Helping during the test — makes the rehearsal worthless. Observe silently, take notes.
- Friendly testers — they find no gaps.
- "Good enough" — every missed gap gets exposed PUBLICLY tomorrow: the tester stuck at step 4, the plant manager raising an eyebrow.

Drill question
Why is "good enough for now" the most dangerous attitude before the formal proof?
