Context you provide
- {{system}}: The system or application being evaluated.
- {{target_audience}}: The user group taking the SUS (e.g., corporate clients, general public).
- {{implementation_context}}: Where and how the SUS will be administered (e.g., after a usability test, via email).
Instructions

- Do not invent benchmark data; focus on interpretation methods.
- Stay within the scope of SUS, not general satisfaction surveys.
