Completing the Usability Test Cycle
Usability testing, and user-centered design in general, is an iterative process. The usability test approach described for VoiceXML code prototypes should be repeated at least once before the product is deployed to make sure that no usability issues crept into the product while the previously identified usability issues were corrected.
Closing the Loop with Users
The last step in the-user centered design lifecycle related to usability testing involves following up with users.
If you followed the process, you should have a good product for deployment to users. It's a good idea to follow up to see whether your users agree, and in the process get input that helps you make the application even better, identify potential new features for the application, and identify potential new applications.
You can follow up with users in a number of ways:
Automated data collection tools built into your application or platform
Whatever method you use, it's important to find out what users like about your application, what they don't like about it, and what they would like to see in the future.
