RCA, 5-Why, and Evidence in One Trainer.
Trains 5-Why sequencing and mechanism literacy
How to use this simulator:
Read the scenario.
Don’t overfit to any one symptom — look for the business mechanism.
Scan evidence.
Use metrics + noisy sample data as sanity checks.
Select contributing causes.
Filter noise/decoys; think impact, not vibes.
Nominate a primary root cause.
Choose the mechanism that best explains the pattern.
Set confidence.
Rate how sure you are — calibration trains judgment.
Score / Iterate.
Hints teach C&E logic; 5-Why builder sharpens causal sequencing.
Unlock Instructor Mode.
At 100% (or anytime), compare to reference reasoning.
