Last year I wrote an article on using surveys in user experience (UX) for the excellent UX Mastery. The piece covers what a survey is, how they can benefit the design process, what to consider before writing a survey, creating an effective survey (writing good questions etc.) and an introduction to some tools.
UX Mastery is a great site with some excellent content including a resources section, with a nice overview of UX techniques and an extensive list of tools. They also created a fantastic video on what UX is, which is worth checking out.
I hope you like the piece on Surveys.
Let me know your thoughts on using surveys in UX or if I missed anything.
