testing _________ [the reason you’re interrupting them] 
and I’d love to get your feedback [what you want from 
them] – you’ll get a $5 Starbucks gift card [what they’ll

3. Follow the script. 
Stay on script. You can even tell your participant – I’m 
going to be reading from a script – if it will make it 
easier to do. 
Staying on script will ensure some rigor to the study.

4. Be a good moderator. 
If you want to ask a follow-up question, avoid 
keywords, adjectives, and hints. 
Here are some examples for what to avoid: 
“How would you pick it up in store?” 
“How much does this app rock?” 
“It’s hard to find, isn’t it?” 
You need this item today, 
what are your options? 
What do you like? What 
would you improve? 
What are you thinking?
