I've created a 3 question survey to measure quality customer service. I plan to use this form during the year and it may go out to the same individuals during the year. If I select the box to avoid ballot stuffing, once they answer the survey, they cannot answer it again, which works as designed. However, If I want them to answer the same questions 4 weeks later AND I want that tabulated on the back end in the same evaluation form so I get the long term result of satisfied, not satisfied, etc, will the check box to prevent ballot stuffing prevent them from answering the same survey 4 weeks later? Seems it would. I know I can set it to not allow responding after a period of time but within 24-48 hrs they could still ballot stuff. It would be fine the first time "Jill" answered the survey, but a month later, I would have to uncheck the ballot stuff feature.
So what is the solution to this? Or best practice. I'm measuring customer service between staff and other internal employees. I want to periodically send out the survey if they received help, but also want to avoid friends of staff ballot stuffing to artificially increase the measure.
