If you had to poll the users that don't use your product on a regular basis, what are the 3-5 questions you would ask them, to better understand their needs and reasons for dropping out?
- Do you know what our product do?
- Which features do you find the most useful?
- Why did you choose to do this over that?
- What would make doing your work easier?
Globally if I can give an advice, try to ask open questions.
