I'm trying to find out if something like quality labels or A-labels exist out there for software vendors. A company I'm working with was asking this question a while back. Say they are interested in buying software from a certain vendor, they want to send this vendor a list of questions and see if the vendor has a quality label or A-label or if they would like to try and qualify for one. But I'm not really sure something like this is feasible or exists and moreover, is it trustworthy? What's your opinion about this or do you know of anything existing like this? Thanks!
