For instruction within a professional org, we utilize checklists for the specific parties to self-assess their "products". Because there is some unfamiliarity with the subject matter, we initially approached the checklists using second person to feel more approachable.
Example: During keyboard testing, can you clearly see where the focus is on the page at all times?
However, I think it may be better to be more direct, removing second person as checklists are instructional and direct.
Example: During keyboard testing, is focus visible at all times?
Is there a rule of thumb that applies here?
