If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which desk feature was difficult to find?
What booking rule was unclear?
What information would help you choose?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: users cannot tell which desks have external monitors.
2. An unclear rule identifies uncertainty about eligibility, timing or shared-space use before reserving a desk. Explain the current policy and support route, without inferring personal entitlement or availability from a respondent's expectation.
3. Turn the requested improvement into a testable next step. One illustrative action is: publish accurate equipment details for each area.
