Just create a collection called "Customer Feedback" and on the form for that have a drop down for yes, no and maybe some comment field.
When ticket is resolved, have it assign the ticket to the user and go into an "Awaiting Customer Feedback" status when when they open the form in that status it gives them the ability to leave feedback (make that the only option). When they click that give them the YES/NO option then based on that answer have a descision in the workflow that does something.
Hope this points you in the right direction
We used this doc (http://community.landesk.com/support/docs/DOC-24952) to tweak our OOTB incident process to send a survey for every resolved incident. You can set the calculation to send at different intervals.
Hope this helps.
