Procedures:

• Take five minutes to talk with your partner(s) about (1) who is delivering tests first and (2) any other commitments they have to user testing, or being user tested upon
• For groups working with more than a simple pairing, or a longer test, ensure that simple pairings take priority, since they should be finished in 30 -40 minutes.   
• Start Tests in a suitable location 

Facilitation style: 

• You are an observer most of all.   Watch the user do what comes naturally. Don't help.
• Much of the time you'll just be prompting them with questions, then encouraging them/reminding the user to think aloud about what they're doing and thinking.  
• In almost all cases, don't answer their questions (until after the test). 
• Use everyday language, not in-house jargon, unless you are testing someone familiar with technical jargon.
• Repeat: don't help!   Keep encouraging the user to think aloud.
• Stick to your Script and Write everything down. If a task is part of the test, note the time it takes each user.
• Notice the user's behavior, and note every occasion the user:
• hesitates, worries, or is forced to think
• misunderstands something
• gets frustrated or annoyed
• gives up.
