Identify the tasks
| Part of use | Questions to address |
|---|---|
| Setup | Can users prepare, fit, connect or configure the product? |
| Main operation | Can they complete the intended measurement, intake or activity? |
| Interpretation | Do they understand results, warnings and the next action? |
| Errors | Can they recognise and recover from an error or invalid result? |
| Continued use | Can they manage charging, cleaning, consumables and maintenance? |
Mark tasks where an error could change a result, interrupt use or cause harm. Explain why the selected tasks reflect the proposed use.
Describe the method
Include recruitment criteria, participant numbers, relevant abilities, experience, language and training. State the environment, task instructions, assistance and measures of success. Explain how participants and conditions represent the intended users.
Report outcomes in full
Give task completion, errors, misunderstandings, assistance and abandoned tasks alongside successful results. State denominators and distinguish observed behaviour from reported confidence. Explain changes made after testing and whether they were checked.
Account for everyday burden
Cover learning, charging, cleaning, recurring costs, dexterity and caregiver effort. A brief coached demonstration alone does not establish that a product remains manageable in everyday use. State limitations such as a small sample or groups absent from the study.
Material to include
Supply the protocol, results, relevant instructions and a clear task-to-evidence index. Edited promotional footage cannot replace the findings. Use the context worksheet to keep the users and setting consistent.
