R Apps is producing a smartphone app that allows diners to rate their favorite dishes at their favorite restaurants, and the information collected is going to be used by potential customers to see what items are most popular and where.
On the restaurant side, the information can be used to gain insight into what dishes were most popular and to rate the quality of the service.
Design a questionnaire of no more than five (5) questions of the appropriate type to capture this information from customers.
What incentive do you think will be most effective in encouraging diners to download the app and submit replies to the survey?
