Thought Provoking Questions

You are a member of a team that has been asked to evaluate a prototype PDA-based application for calculating drug dosages. Based on what you know about usability testing, what kind of test (or tests) might you do and why?

Thought Provoking Questions

Is there a human-technology interface that you have encountered and you think needs improving? If you were to design a replacement, what of the analysis techniques you read about would you choose? Why?
