Question
Design a feature to improve driver retention for a ride-share app.
HardTimer starts with your rep
H3+ Assumption+ Metric+ Tradeoff
4. Cut (prioritize the list)

Focus on the top 2–3 problems with the highest impact on retention and within our control.

  • •  Earnings predictability (top signal in driver surveys)
  • •  Low engagement / feeling of isolation
  • •  High commission sensitivity
Assumption

Drivers churn most in the first 90 days due to earnings uncertainty and low attachment to the platform.

A repeatable loop

Practice the decision,
not a script.

Build judgment the way athletes build instinct: make a call, inspect the evidence, then train the weakest move again.

Why deliberate practice works

Less content.
More signal.

Each rep leaves evidence: what held up, what broke, and the exact skill worth practicing next.

Graded, not watched

Every rep is scored on a real rubric, so you see exactly where your thinking breaks.

Reps, not marathons

15-minute structured reps beat a 6-hour course you never finish.

Signal, not vibes

Track Structure, Prioritization, and Metrics over time — improvement you can measure.

Frequently asked questions

The essentials, clearly answered.

No vague promises. Here is what the free tier includes, how scoring works, and which PM loops you can train.

What will the founding beta include?

Invited testers can complete rubric-scored practice cases. The current free plan is designed to include 3 full evaluations a month; final beta limits will be shown before an account is created.

How does scoring work?

Your answer is evaluated against a consistent 7-dimension PM practice rubric. Results show the engine actually used. If production scoring is unavailable, scoring pauses, no result is saved, and you can retry later.

Which skills can I practice?

Product design, strategy, estimation, execution/root-cause, metrics, and behavioral reasoning through authored practice simulations across familiar product contexts.
