How it works
Enter practitioner evidence
The method uses states required by the test plan, required states prototyped (%), decision branches represented (%), relevant error paths represented (%), planned tasks runnable end-to-end (%) rather than generic rating questions.
Review the output and gap
Use the generated structure or calculation as a draft, then validate the weakest evidence with representative users.
Frequently asked questions
What does the Prototype Coverage Checker produce?
It uses states required by the test plan, required states prototyped (%), decision branches represented (%), relevant error paths represented (%), planned tasks runnable end-to-end (%) to produce an input-linked UX output, evidence signal, and next action.
Is this a substitute for user research or accessibility testing?
No. It structures supplied evidence and planning assumptions. Validate important decisions with representative users, assistive technology, source data, and qualified review.
Do all fields affect the result?
Yes. Every entered quantity, bounded choice, or written evidence field changes the calculation, structured output, explanation, or recommendation.
Is entered information uploaded?
No. The calculation runs in your browser. Do not enter participant names, recordings, credentials, or other sensitive information.
