I have an opportunity to survery a very large number of users before the release of a new version in January. I was considering using the net promoter survey but then read some articles that were critical of NPS. The release is on a particular page of a web app and will grab the users while using that specific tool. I've used SUS in the past but typically with internal users that are not critical enough.
I'm looking for advice about which survey I might use. It would be great to use one like NPS or SUS that can be measured and benchmarked later. Anyone had any good results doing an automated "before and after" release survey?
