Summary: Surveys are often over-used or mis-placed as a research technique that many teams rely on to figure out usability and user experience problems. Understand the limits and opportunities of the tool and instead either don't lean on it too heavily or use it as an adjunct to reach a wider audience--as part of a qualitative user research project (user interviews).
When Surveys Fail You
Surveys are great, except when they are not. Surveys are often used as a way to gather usability feedback. This makes sense, after all questions like: Do users use your site or app? Do they find it valuable? What do they want? are perfectly reasonable questions to ask your users. So what is the problem with surveys for user experience questions?
First, be clear that surveys are a market research tool. That means they are not entirely appropriate as a usability or user research tool. Why?
