I was setting up a UX questionnaire for an e-Commerce site and liked the idea of the SUPR-Q questionnaire as a UX metric. I then read in an article that it's not free? How is this - is this correct? Does someone actually own the intellectual property on a questionnaire? If so, what's to stop me creating my own similar questions to ask?
While Jeff and Measuring U do own the rights, they also say "You are welcome to use the SUPR-Q questions without purchasing the SUPR-Q license. Please simply cite this reference (Sauro, 2015)"
What you miss out on by not purchasing is the calculator and the industry benchmarks.
