Create a usability test plan with tasks, success criteria, a moderator script, observer notes sheet and a severity-rated issue list.

Help me plan a usability test. What is being tested (prototype, flow or live feature): [TEST_SUBJECT]. Who the users are: [USER_DESCRIPTION]. The key tasks users should be able to do: [KEY_TASKS]. Number of participants and format (remote or in person): [PARTICIPANTS_AND_FORMAT]. What decisions this will inform: [DECISIONS_TO_INFORM]. Produce: a test plan with goals, questions to answer, and what is out of scope; five task scenarios written as realistic situations without giving away the interface wording, each with a success criterion, an expected path, and a time limit; a moderator script of about 300 words covering welcome, consent, think-aloud explanation, neutral prompts such as "What are you thinking?", and wrap-up questions; an observer note sheet table with the columns Task, Success (yes, partly, no), Time, Errors, Quotes, Observation; and a findings template with a severity scale from 1 to 4 and the columns Issue, Evidence, Severity, Frequency (x of n participants), Recommendation. Calculate task success rate and average time from a table of results with the arithmetic. Remind me that small samples find problems but do not measure rates precisely. Do not lead the participant, and do not invent results. Recording and consent practice depends on local rules and your organisation; mark it [VERIFY]. Tool features for remote testing differ, so flag them [VERIFY]. Add a worked example with invented figures: 6 participants, task 1 succeeded for 5, task 2 for 3, with times in seconds of 40, 55, 62, 48, 90 and 51 for task 1.
