One of the first rules in the UX field is to not ask users what they want nor what they prefer, but is there a reason to not ask which tools they have and if they use them?
I have to redesign a software, one of the main problem is that it does not interact well with some other tools/programs that some users currently use: that is something I know from my contextual inquiries. I would like to know if this is common among most of my users, but I cannot afford more contextual inquiries. This is why I am considering a survey with specific questions on which programs are installed and if the users know them well enough. I will base the new design based on these information.
