Startup / LEARNING STUDIO

Choose a problem worth solving

I have a product idea but do not know whether it solves a need.

Change direction and availability

A problem hypothesis card and evidence plan.

2026-10-26.2 · 40 minutes estimated; work in several sessions

Saved on this device; sign in to import explicitly.

Next · 5–15 minutes

Spend ten minutes describing one user's recent incident.

Prerequisites and goal

A specific group and situation; a product is not required.

Start with diagnostics; skip explanations you can already apply independently.

Bound the situation and behavior

Describe who is trying to do what, the trigger, existing workarounds and costs. Students need AI is unbounded; group leaders losing changes during submission is observable. Users, buyers and payers may differ; record each.

Order evidence by risk

List assumptions about existence, severity, access, willingness to change and delivery. Test the assumption that would invalidate the idea first. Praise is opinion; costs and active workarounds are behavioral evidence, but not market-size estimates. Define continue, narrow and stop conditions.

Worked example · fictional

From a problem to inspectable work

Fictional: two friends praise a proposed campus AI assistant.

  1. Praise does not identify a situation; ask about a recent incident.
  2. Both mention version confusion, but only one paid for a workaround.

Narrow to version checking by group leaders and observe a real handover; willingness to pay and market size remain unknown.

Failure case and repair

Treat friends saying they would use it as validated demand.

Attitudes become false behavioral evidence and encourage premature features.

Investigate a recent event, costs and counterexamples.

Glossary
Evidence and inference
Evidence is traceable material or observation; inference is an interpretation requiring assumptions.
Transfer practice
Apply the method independently in a new situation, checking which conditions have changed.
