Five participant test plan.
Recruit five India-based desktop web shoppers with a mix of checkout familiarity and payment preferences. Ask each to update quantity, change address, choose delivery, review cost, choose a simulated payment method, recover from a simulated failure, and identify the confirmation state. Observe hesitation, wrong turns, missed controls, cost comprehension and recovery confidence. A task succeeds when the participant reaches the intended state without moderator help.
Limitations: small qualitative sample, simulated payment, no live Amazon transaction, no measured baseline. This plan has not yet been run. The current browser walkthrough is interface evidence, not a participant usability test.
