Last week I got this paper from dr. Tilde Bekker about Value Laddering. Value laddering is a technique to interview users about their experience with a product, based on following through on answers by asking ‘why’ several times. This site also has a pretty thorough description of the process.
Hopefully I can finish the GUI and prototype this week, so I’ll have time to evaluate my concept with users. It would be great to use the Value Laddering technique for this. I need to find out how to do it exactly and write a plan!
