Product Discovery interactive guide
The assignment
Build an interactive guide that teaches YOU Product Discovery.
✳What Saurab shipped
Product Discovery Lab is a gamified, no-login web app organized into modules across Understand, Explore, and Decide categories, with ranks, XP, and badges tracking progress across nine modules. Content covers user and market research, jobs-to-be-done, customer surveys and interviews, the Five Whys technique, and using experiments and MVPs to validate ideas.
✳Our read on this build
Saurab shipped a deployed web app you can open. Parts of it sit behind a sign-in, so this read leans on what is public plus Saurab's own description.
What it demonstrates
- The curriculum names real discovery craft — jobs-to-be-done, user interviews and experiments — which is the difference between teaching discovery and describing it.
- It also tries to be about you rather than about the subject: a saved account and progress tracking.
What is not shown
- Nothing public points to a moment where the learner has to commit to an answer — from outside it reads closer to structured reading than to practice.
Take this awayThe reason this shape works is friction in the right place. A build that makes you choose before it explains is teaching judgment — the part of discovery that never transfers from reading.
✳Why this quest matters
Discovery isn't a chapter you read — it's a muscle. The strongest builds here force a decision out of the learner, because the fastest way to internalise discovery vs. delivery is to practise the judgment call, not memorise the definition.
✳What separated the strongest builds
The learner has to make a call
The builds that landed put a decision in front of you — a scenario, a branching choice, feedback on your answer. The ones that didn't were articles with a nav bar.
Discovery vocabulary that holds up
Mom Test interviews, opportunity trees, riskiest-assumption tests, small prototypes shown to real users — the framing that separates discovery from delivery.
It teaches you, specifically
Your product as the worked example, your notes kept, your progress tracked. The brief said teaches YOU — and the generic explainers all read interchangeably.
No numeric scores are published here. These pages are written reads of what each builder shipped — the build is the point, not a mark out of a hundred.
