Yоu аre cоnsidering stаrting а new business оffering billing services to doctors offices; a problem you think they struggle with. You want to test if there are even customers that would want to use your services. It's difficult to even find people willing to speak to you, so each lead takes a lot of your time. While trying to plan your survey, you have thought of two options: Option 1 (Ask Generally): Provide a chance for your survey respondent to tell you what issues they're encountering in billing. This might lead to discussing your solution, but lets you hear about what problems they are actually having -- maybe a better business idea could come from these discussions? This option takes more time. Option 2 (Provide Solution): Tell your survey respondent about your idea instead of asking what issues they're encountering in billing. You would get more exact information about your current business plan -- hopefully they're experiencing the same problem and you get data on topic. This option takes less time. Taking into account your time and the data quality, which option would you pick and why? Explain in 2 to 6 sentences.
