RESEARCH METHODOLOGY
Measure completed decisions, not just clicks.
Traffic and calculator starts are useful signals, but they do not show whether a product improved the user’s decision process.
Completion clarity
Can the user identify the result, key assumptions, limitations, and next step without searching elsewhere?
Scenario understanding
Does the tool help the user compare meaningful alternatives rather than present one unexplained output?
Action continuity
Can the user move from the result to a related guide, checklist, comparison, or saved plan?
Return usefulness
Does the experience give the user a reason to revisit and update assumptions as conditions change?
Error and trust signals
Track corrections, abandoned workflows, confusing inputs, support questions, and discrepancies reported by users.
