The assignment
Build an interactive guide that teaches YOU Product Discovery.
SuperPM is a deployed web app for Product Discovery accessed through a Google or email sign-in flow.
Niraj 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 Niraj's own description.
What it demonstrates
What is not shown
Take this awayUseful as a structural reference. The gap worth closing in your own version is the feedback loop: telling a learner they were wrong is where the learning actually happens.
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.
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.
