How would you run a usability test for a new application form?

Recruit participants representative of the intended audience and give realistic tasks without explaining how the interface works. Observe task completion, errors, hesitation, and recovery, and ask neutral follow-up questions. Obtain appropriate consent and avoid collecting unnecessary sensitive information. Distinguish a user’s stated preference from observed task difficulty. Group findings by severity and recurrence, then revise and retest the most consequential issues. A small qualitative study can uncover problems, but it does not by itself provide precise population-wide conversion estimates or prove that no usability issues remain.
