TIP: Don't!
Don't to early Survey while you are doing Client/Customer Discovery! You need to connect with these early adopters at a differnt level. A Survey is for quantifying theoritical values to measure: (left v right v top v bottom)
Early we are trying to measure which feeling, which direction is the strongest and also evaluate WHY. Why is not a question that gets answered with survey.
