We are building a web based solution right now and it is almost ready to roll out, but I felt we have not really verified our initial hypothesis about the problem domain we are trying to solve. So I decided to attend a conference where most attendees are our target users. What I want to get out from the conference are
1) verify if our initial hypothesis is true
2) if the hypothesis is true, is our solution addresses the problem in a user friendly way.
3) will they use or eventually buy it.
I only have about half day.I am thinking a few options here:
a) walk around and show demo to people.
b) do more listening and ask questions.
c) collect as many business card as possible, and connect after the conference.
Any suggestion on how i can do these most effectively? thanks
