So What About Synchronous Remote Usability Testing?

The previous week, I posted part One of this article.

In order to integrate the user into the design process at the earliest possible date, it is customary to develop a low-fi prototype which will allow initial evaluation of the overall design. We are however faced with a problem if we want to combine the qualitative feedback of synchronous usability testing with the advantages of non-biased remote testing. How can both approaches be combined?

Yet again, technology should hold the answer to this question:

Requirements for Synchronous Usability Testing:

• test-user and moderator need to be connected via the Internet
• a shared screen needs to be in place for both to view the prototype
• a live audio connection should be in place for synchronous communication
• the data of the test-session needs to be recorded (audio, video recording of all mouse movements)
• recorded data needs to be stored for instant retrieval

Optional requirements which may increase the quality of the session:

• information and tasks should be visible to the test-user
• moderator’s ability to integrate questionnaires which the user can fill in his own time
• the moderator can change parts of the prototype whilst conducting the test
• comments and annotations can be included on-the-fly
• test-user and moderator can be connected via a live video-feed

Usability Test: Methodologies

The overall test should allow the following methodologies:

• Thinking Aloud (test-user must think aloud and express what he thinks or misses in the prototype)
• Wizard of Oz Prototyping (the prototype can be changed on-the-fly for instant ratifications)
• Team Observation: (the rest of the production team follows the usability test, make notes and come up with alternatives)
• Formal and Informal Tests
• Click-path Analysis
• Use of Questionnaires

Next week, part THREE of this article will follow.
