Selecting the right people for the right task. Well, in our case four people have to do it all.

After reading the preparation and conducting usability testing session for rigorous empirical evaluation, something stand out to me. How should we selecting the right people for the right task, both the usability designers and usability participants.

Having a facilitator to help the session to go smooth. A prototype executor help individual task detail. A quantitative data collector to help record error number. task timing, and etc. A Qualitative data collector to record any observation or emotion data from the participant. And of course other supporting actors to help interact with participant for the specific task. Feel like this will be a room full of people. Seeing photos about the UX Lab at Bloomberg LP (pg. 517), the designers illuminate distraction by putting different people in different room to do observation, recording without the participant’s knowledge. And actually only a few people to interact with participant.

But in our class research group, four people are actually doing all the tasks during an usability testing session. We need to better understanding each team role match with the right team members. Maybe one person will have more than one team role. Also we can rotate team role to help each team member to learning different part in this process. Another thought, every usability testing session should be a learning process for the next, we will have to address different issues or problems, so that we can conduct a better session next time.

Picking the right usability participants should be a balance process. Although all participants should be potential user of our product, picking different knowledge level user is important, so the result can better reflect the general population of users.

Be prepare and pay attentions on the unexpected during the testing session, come up with better and more intuitive ways to gather user data, this is my advise. Practice makes perfect!
