Best practice
When using "who does", ensure the context is clear and that the subject of the action is either previously stated or easily inferred. This avoids ambiguity and ensures the question is easily understood.
Common error
Avoid using "who does" when "what does" is more appropriate. "Who" refers to people, while "what" refers to things or actions. For example, use "What does this button do?" not "Who does this button do?".
