Ask concrete feedback questions
Concrete questions are more impactful than general questions.
Instead of asking vague questions like "What do you think of this?" try to be specific and focus on specific aspects of your design. For example, you might ask, "What do you think about the layout of this page? Is it easy to navigate?" By asking concrete questions, you'll be more likely to get targeted and actionable feedback.
Asking concrete questions helps people think critically about their workflow.
By focusing on specific aspects of your design, you'll encourage your reviewers to think more deeply about their experience with the design. This will help them identify any issues or areas for improvement that they might have missed otherwise.
Make room for catch-all questions at the end.
While it's important to ask specific questions, it can also be helpful to leave room for more general feedback at the end of your presentation or video. This can be a good way to capture any thoughts or observations that your reviewers might have that don't fit into a specific category. One of my favourite catch-all questions is "What is missing or felt off about this prototype?"
Overall, asking concrete questions is a valuable strategy for getting async design feedback. By focusing on specific aspects of your design and leaving room for more general feedback at the end, you'll be more likely to receive targeted and actionable insights that can help improve your work.
