This is a very broad question:
I am looking to see what my options are for adding questionnaire functionality to my website.
So Let me know if you can recommend a well developed questionnaire software or your approach (i.e. Use all SAP modules, Use xxxxx software, send data to your SQL Server, then do your reports with Tableau, etc, hire xxxxxxxx corp this small business developers to do everything, setup these APIs, Use these 3rd party software service providers, etc. )
The short storybook scenario might be:
Front End: I provide several users(100-5000) with a code(via email), they logon to a website, they are prompted with a questionnaire. They fill it out, Mostly multiple choice but may have some open text they can enter in, done.
Back End: After several people take the survey, the data will be ran through a report program to provide statistical results and charts.
