this looks terrific! I really like the wording of your qualitative research question, very appropriate with use of words "experience" and "how". I also like how you described why you chose to do interviews. It isn't required that you verify your ideas with your participants, though it is a very nice idea. I think you may be surprised by how people are often comfortable talking about ideas that you feel would be hard to talk about. Would be great if you can get someone on your team with qualitative research experience to guide you.
